I can agree that a lot of ppl that have made comments about how this will suck big time have made some stupid biased statements, but there are some things about this movie that irks me as well.
Forget blue hair and green skin... I could care less about visuals. I think Goku's character is just all wrong. Just like that one guy said about him being reserved about fighting. Goku would NEVER say something like that. He'd be training his ass so he could beat that guy. I can't tell from the trailer, but hopefully they didn't get rid of the carefree and innocent qualities of him.
It seems like a typical formulaic Hollywood movie. Underdog gets bullied in the beggining, then he finds out there's some latent potential ability or special power within him and that he must use it to beat some bad guy. He also gets the girl in the end and there's some mushy kiss scene (already seen in the trailer).
As for the Goku should be Asian argument... He IS based off of Sun Wu Kong who is technically Asian, but I guess since he's an alien I'll let that one slide lol. Wow I typed a lot. Probably gonna get a lot of tl;dr.
