Wow, all I can say is wow... Saw the movie, and here is everything wrong with it:

1)Goku in general. He is supposed to be innocent, dorky, oblivious, etc; not a nervous pervert. Where is his tail? Why was in in high school (he had no education)? Why did he have crappy hair with no banes? Why is making energy attacks a challenge (they came easy to him)? Also, what happened to Goku being mean when he was a baby? And the waterfall accident? Also, his attire. Goku always wore his duds and never liked normal clothes. Plus, the colors are important to get right, he looked like Vegeto in one scene.

2)Supporting Characters: Bulma should have had more blue in her hair. She wasn't a bad ass, more like a pissy whiny wimp. Why didn't she ever act like a slut (its her thing)? Master Roshi should have been bald with a beard and mustache, what happened here? Where was his turtle shell? Cane/stick? Sunglasses? Why wasn't he a super perve? Why is his Island on a peak in the city? Where is the tropical look? Yamcha is supposed to have black hair, not blond. And since when was he butt ugly? Chichi was never a whore and was usually very conservative. She wouldn't be flashing cleavage around and acting slutty, thats Bulma's thing. Grandpa Gohan died when Goku was a kid BY Goku.

3)Missing (main) Characters: Krillin, Puar, Ox King, Tien, Chiatzu, Turtle, Flying Nimbus, Power Pole etc

4)Energy Attacks are supposed to be energy, not "element bending". This isn't avatar bull-crap

5)Great Ape Form, What in the world is up with the 8 foot tall great ape? What happened King Kong sized? And no tail? Looked like a big werewolf.

6)Shenron, Speaking of sizes, what in the heck was Shenron's deal? Excuse me, "Shen-Long" as it is said in the movie. Shenron is miles long and massive. He is supposed to talk and the sky is supposed to turn black and stormy. He is also supposed to be green.

7)Kamehamaha Wave Attack, its only two friggin movements, not 20,000 useless ones. Also, no one "draws" energy to do it, thats the Spirit Bomb. Also, when used, you get pushed back, not thrusted forward. It isn't a hook-shot.

8)High School, What is up with the school? Goku never attended school, only his son did. Chichi got mad at him cause he never went. High school is irrevelent to the entire show.

9)Power ups, Lack of long power up scenes. Every DBZ thing had useless long power up sequences; but thats what made the show the show. NO power ups in movie at all.

10) Environment, the world these characters lived in had dinosaurs, deserts, etc. Also, it had futuristic cities. Neither were depicted in the movie.

I'm sure there are other points I missed, but these are what bugged me the most.. Feel free to add on if you found any...
