This movie is going to be a total disaster. -_-' Look, I’m a massive fan of DB, DBZ, and Dragon Ball GT, but this feels like it has almost nothing to do with the actual anime or manga. Adapting Dragonball is basically impossible, and it looks like Fox just turned the cartoon I loved watching as a kid into a complete joke.
1) Goku is an 18-year-old high schooler now? O_o That is just absurd. Based on the trailer, the tone seems way too serious, whereas anyone who actually watched the series knows Goku was a kid—around 10 years old—and he was pretty much a moron. If they were setting the story during the tournament where he fought the reincarnation of King Piccolo, you could maybe justify him being 18. But since when was he the "chosen warrior"? O_o As far as I remember, Goku is a Saiyan sent to Earth in a space pod to destroy it. He was found by Gohan—his grandfather—whom he accidentally killed after turning into a giant gorilla during a full moon, not Piccolo. And he doesn't even meet Bulma until after that whole incident when she's looking for the four-star dragonball.
2) Roshi bears zero resemblance to the character we know from the manga or anime, either in terms of personality or look. He's supposed to be this old pervert;
3) The Dragonballs weren't created by some Buddhist sages. They were created by a Namekian who had to split his positive and negative sides apart so he could succeed "god" (Kami) in the DB universe. The negative side is Piccolo and the positive is Kami. Also, if I recall correctly, the Dragonballs have nothing to do with the apocalypse. At least not until Dragon Ball GT. People hunt them down because they can grant any individual wish;
4) Krillin, the guy who's been by Goku's side since childhood, isn't even mentioned, and
Pilaf, the one who released Piccolo, isn't in the movie either.
5) Mai was never a fighter, let alone someone capable of transforming;
6) The Trailer... I don't even know what to say. It looks like some low-budget adaptation
Overall, this movie deserves an Oscar for "epic fail." Subjectively, I hate it. The entire concept of the Dragonball universe has been rewritten. I assume they're making this for an audience that has never even heard of Dragonball.
I think most fans of the series will agree with me that this movie is a complete failure of an adaptation for the legendary Dragonball. 👎
