I would have to say

One Piece - which I'm glad there still dubbing
MAR
Air Gear
Prince of Tennis - it was a lot better than I thought it would be

and many more that I cant think of right now.

My name is earl I loved that show. Also I remember watching a Sonic show, it left on a cliff hanger.

A show I was upset about cartoon network canceling was samurai jack, that show was epic and quite frankly way to good for cartoon network standards.

I have to say Twin Peaks...
Quite strange of me but I did take an interest when I discovered it.

Common law, I hate that they canceled it. It had a great opportunity of becoming one of the best crime shows. For me it was better that csi and ncis.

The Napoleon Dynamite cartoon was actually pretty funny. Everyone thought it was horrible though and nobody watched it so that's why it got cancelled. It didn't last very long. It was still pretty funny though.

Ed Edd and Eddy wasn't canceled, they just finished, they had a big movie and everything. Anyway the show I wish would have got more love was pushing daisies, about the pie man who raised the dead, that show was like a twisted faerie tale

I don't know if anyone remembers it, but the show Terra Nova, it was a prehistoric show where they would live along side dinosaurs on a new planet because the Earth became uninhabitable. I would sit down on Mondays and enjoy watching it when it came on, I really enjoyed watching the show. I would actually look forward to Mondays more because of this show. My parents would record it and I thought it was great and the show only got better. But for some reason they ended and cancelled the show and they said they would move it to another network which never happened. I really did enjoy watching that show, and they cancelled probably for some other lame show to take its place. 

Samurai Jack. That was really hard when they canceled that show. Ultimately, when they took down Toonami, and put in all those crappy shows that only lasted for a 2 years. Toonami lasted for over 10, if I am not mistaken.

I guess that I should reply to the question in my own topic now :slaps forehead:  Maybe I was waiting because I have so many.

Young Justice -- I thought the design of this series was great, think it was canceled too early only so that Teen Titans Go! could be put on the air. I enjoy animated shows that have constant character and story development, and this one even set up for a third season even though they knew it was unlikely going to happen.

The Zeta Project -- The idea of this series was great: a machine designed for killing that doesn't want to kill anymore, meanwhile its developers see this as a malfunction of a still-dangerous machine. This is one of the only DCAU series that wasn't given enough of a chance to run its course.

Samurai Jack -- The artistic style of this series was amazing, and I hated to see it go. I didn't care that he never made it home, I just wanted to see many other adventures.

Sir Arthur Conan Doyle's The Lost World -- I enjoyed this series and was angry when it ended in a cliffhanger and was suddenly canceled (a new season was originally planned but the network decided instead to drop it.)

Futurama -- ... though they did eventually bring it back.

Adventures of Sinbad -- This series ran around the time of Hercules and Xena TV shows and had a feel similar to them. But 44 episodes wasn't enough.

Celebrity Deathmatch -- This series ran 100 episodes, but it was the type of show that was oddly entertaining and would have never run out of ideas.

Foster's Home for Imaginary Friends -- The series had a nice run. It was a guilty pleasure of mine to watch, though, so I wanted more.

Trading Spaces -- The only reason I really wanted this series to continue is that I had a family member who worked behind the scenes in the art department. The behind-the-scenes truth about this show is that the home owners and those on screen only did part of the work. There were other staff that helped cover many of the jobs that were never shown on camera. Even then, I was told stories how, after the few days were up, if projects were not finished, the show's crew left, leaving them unfinished and the home owners' responsibility. Instead, if they couldn't finish the curtains in time, they would be barely hung or held up by duct tape in the back to make everything presentable on camera.

X-Men: Evolution -- This series ran a decent number of episodes, but they opened up new plot ideas in the middle of the last season that never went past the individual episode. I wanted those to continue.

Mystery Science Theater 3000 -- The series ran for almost 200 episodes, and I still wanted more. It was entertaining in a unique way and as long as there were bad movies still in existence, so could they have had more episodes.

The biggest shows I liked, The Cleveland Show and Futurama are being canceled .
This is sad, I really like the shows and with them being canceled, I don't know what to say

Personally, I think Comedy Central bought and brought back Futurama to get a quick ratings bump.

After 5 years canceled, in 2009 it was revived using DVD sales which would "test the waters" for current popularity. However, after the movie-release time frame, the two "seasons" produced were made half-seasons and split over 4 years. The last half season hasn't even aired yet, but they probably decided at the start of last season that they were going to cancel it, but this gave them a long break before having to announce it.

The Hard Times of RJ Berger: They just went up and canceled this show before we could find out of RJ's the father of Lily's unborn baby.

Futurama: I'm really pissed off that canceled this show. This show got no respect. It could have went on for bout 3-4 more seasons. Hell, Family Guy got canceled, and it's going on 8 years since it came back.

The Cleveland Show: It's an ok show. The bright side of this is Cleveland might be back on Family Guy along with his new family. Rallo and Stewie would make a great duo.

LA Complex: The CW is extremely wack for this. They were building characters and story lines for Season 3. Season 2 ended with Rook murdering Darius for intentionally outing Kal's homosexuality after being paid off, but was innocent, so we'll never find out who really did it. This show really didn't get the advertisement it deserved. It was only Tuesdays, but moved to Mondays including 2 episodes for the last 2 weeks it was on the air. Hell, some people didn't even know their was a 2nd episode. This show really got screwed. Hopefully there's petitions that want this show back.

In The Flow with Affion Crockett: Another good show on a crappy network. Comedy Central could have picked up this show. This show also got a lack of advertisement, and it premiered in the Summer. Also, it came on Sundays which is animation domination night. At least put it on Tuesday where most of the comedy shows our on. This show got a huge raw deal.

Tyler Perry's House Of Payne: This show's series finale ended in a cliff hanger. I hate shows that do that. This was a really good show, and could have went another season, and ended with a proper series finale.

Tyler Perry's Meet The Browns: This show could have went 2-3 more seasons. The final season was 8 episodes, and didn't get a proper series finale. Not sure why this got canceled. They had ratings just as much as House Of Payne though it had a good story line at the time.

Moesha: Another show that ended with a cliff hanger. Does the family get Miles back? HELL! We didn't even find out when The Parkers (The spin-off where Kim and her momma go to college.) were on TV.

Wrestling Society X: I know this isn't a show, but still injustice caused by a dumb network that thinks giant oompa loompas being compete idiots make a great show. It was filled with wrestlers from WWE, WCW, and ECW that never got to hold World Heavyweight gold along with great wrestling talents from top independent wrestling promotions and international talents from Dragon Gate getting national views. It was going great til Episode 4 pulled by MTV because they didn't wanna show Vampiro get hit with a fireball, but they show guys doing far most dangerous stunts on their shows all the time. Series ended with 5 back-to-back episodes during Spring Break to really give the show low ratings and never aired the Season (Series) finale which reveal they were going to bring a new championship title in the mix.

America's Most Wanted: This is a show that's shouldn't even be canceled. This show helps people get justice. FOX got rid of it for what? Lifetime got rid of this show for what?

Sorry if this is to much to read, but I'm a TV-holic. It's just sucks that all these shows got canceled and some got raw deals by the networks they was on. Shows like Keeping Up with The Kardashians still on the air that should have been canceled a long time ago really piss me off. Good shows like America's Most Wanted getting canceled for dumb shows piss me off. Shows that can change lives getting canceled for shows that don't make a lick of sense extremely pisses me off. TV shows these days aren't even filled with actors with talent. It's mostly people like us that get paid to look stupid on national TV.

I'm in the band. I so hated that Disney had to cancell it. reason why: That show was so funny,but thanks to zeke and luther being so sucessfull It got cancelled(Grr Darn you zeke and luther). 2nd pair of Kings Well It's not exactly cancelled,but Dang it disney They replaced Mitchel musso Aka the person who played king brady. and replaced him with darn adam hicks. Aka he's king bos  now the show has gotten compeletely stupid and unfunny since disney made that move. Heck A lot of people dropped that series. And I was 1 of them (again darn you adam hicks)

3 other shows they shouldn't have canceled were Sym-bionic titan, Young Justice, and Lincoln Heights. Sym-Bionic titan could have gone a couple more seasons. Cartoon Network makes some of the dumbest moves and this was 1 of their dumbest. Along with that, Cartoon Network is also stupid for canceling Young Justice. Really didn't see the show til they brought in Static. Matter of fact, that's 4 shows that shouldn't of gotten canceled. Lincoln Heights ended too soon. Really never got the attention It should have got back when it was on the air. Also liked the direction it went with Interracial dating. There's not enough of that on Television, but when their is, people act so ignorant. Some people need a reality check.

I'm really surprised only one person said Firefly. BEST. SHOW. EVER. and stupid Fox had to air all the episodes out of order and then complain that the story made no sense -___- 

After Firefly would be Community but that Commy was recently put back on
