I've said this before and I'll say it again. We have a right to piss and moan about a film being made out of something we've enjoyed for some time now. Look at how many hours of the series and movies there already are, there is no need to make a live action DragonBall film apart from to make money.
If you wanna get REAL technical about it then[Ace Ventura style inhale]; DragonBall was conceptually inspired on a Chinese story from the 1590s called Journey To The West - http://en.wikipedia.org/wiki/Journey_to_the_West - as was the just as popular 70's show 'Monkey!\Monkey Magic!' - http://en.wikipedia.org/wiki/Monkey_(TV_series)
DragonBall obviously added their own ideas once they'd gotten so far with the manga, this eventually evolved into DragonBall Z (and obviously then DBGT). I'd say that because DBZ is the most popular of the three, most of the people that both were fans already and fans for the first time, check this film out because of their knowledge of DragonBall Z, not DragonBall.
Therefore, I wonder why they chose to take the DragonBall series and
bastardise 'Lucas-Rape' it, seeing as the pig/Oolong is one of the main characters in DragonBALL and they're NOT going to put a pig in the film, NOT not going to shine the same light on DB with this high-school car driving thing and they're NOT going to introduce Goku as the child that he was and still is, and.....that's.....the.....point! [inhales frantically]
Not meaning to go off on one, but they're obviously only using the name and the snappy look (like ALL comic to live action movie conversions) so that more people come and watch it and spend money on them dressing up as DB characters and fulfilling some pointless (even though financial) agenda.
[spits] They should have just made something from scratch and stolen the bits that they wanted (images of balls with stars glowing, mention of a possible dragon that grants wishes, super-human fights with some odd demon(s) and some big ass hair. Then they could put in whatever they wanted.
People would have mocked it for being a shit version of DragonBall, but people will do that anyway.

EDIT: And I'm glad someone bumped this thread, I noticed another one was created recently.
