Okay, lets get this one out of the way...
Dragonball Evolution
It seems that with the overall success of comic book movies, and the mediocre success of few video game movies, it seems Hollywood has set its eyes on japanese anime. The one major problem with this is some anime can not perfectly translate to live action form. Dragonball is one of them.
Now granted, with a well done script, and a good team, a live action version of Dragonball could be done, after all an adaption is taking one thing and molding it into something else while staying true to key points, not all 100% of it. Evolution was missing said script and team.
The list for what is wrong with this movie versus what is right is much, much longer, so lets go over what was passable first:
The style of the movie was actually passable, along with some special effects (mainly the power attacks).
Goku himself passed because of one scene. When he was being confronted by the bullies of his school, he mentioned that he promised not to fight them, but also said he wasn't going to run away anymore. So in true Goku style, he allows the bullies to throw their punches, ducking and dodging each one of them and causing them to hit each other; all the while laughing and poking fun in a nonchalant way. Even made one of them destroy their own car when they went after him with a ball bat.
The capsules passed because we believed them as kids watching the anime, so why not believe them now?
Now here is what was wrong:
Gohan (Goku's grandfather) was still alive
Master Roshi was in no way an pervert
Goku's ape form was not only controlled by Piccolo, but was only 7 feet tall
The love between Goku and Chi-chi was more sudden than ever
They called the power moves "Air Bending"
They pronounced Kamehameha "Ka-me-ha-me-ha" instead of "Kamehameha" like every time they mentioned it, they were saying it like they were using it, and somehow, the Kamehameha could act as a CPR method
Yamcha was more lame than he was in the anime (yes it was possible)
Venom was around more than Piccolo
Roshi could jump out of the damn hole they fell into, but instead sat there with everyone all night until Yamcha came!
For the love of all that is holy, do not let your curiosity get the better of you. Skip this movie, or have your childhood stomped on.
