Ok here are some serious problems I see, and I won't even go into the new Frieza form, the first problem is with that red bull guy who beats piccolo, and someone beats Gohan, are you serious?! Let's just say frieza beat Gohan for argument sake even though that sounds absurd already. But anyways lets take the piccolo fight, if we remember piccolo was on par with android 17, where was this bull guy during the Namek saga, the bull guy would be stronger than anyone back then. Also if Frieza supposedly just found him, I am not sure if that is plausible or not, because wasn't Frieza's force consist of the entire galaxy or almost the entire galaxy? I mean yes he didn't care about Earth, which housed the individual that led to his demise, but Goku remained unknown, because he was relatively weak until the Namek saga, with regards to Frieza. But one would think at least one of his forces would hear about this red bull Bull guy who was as strong if not stronger than Android 17.   Second problem doesn't Sorbet and Togama have two more wishes left, because last I check Shenron gave three or two wishes I can't remember which it was and they only used one wish up. Maybe those wishes could possibly remain unknown, and that could be the premise of the next movie maybe to bring back Cell or Buu, or even King Kold. That would have been cool to if this movie was about King Kold's revenge. I wish they would bring more information, and background about that character as I believe he is not only very mysterious, but also could create a very good character development for that character. He is in my opinion as important or even more so than Frieza at this point, because he can tell us about his past, like who was his father or whatever.
