Just know there's a whole lot more great stuff out there than just what Evolution has in store for you -- namely, the anime that it was based on.
What are people saying?
What are critics saying?
The Hollywood Reporter by Frank Scheck
Completely lacking in visual, narrative or stylistic coherence, the film also suffers from cheap-looking visual effects and poorly staged and edited action sequences that will not exactly please the fanboys.
Austin Chronicle by Marc Savlov
Bottom line: costumed Goku and Chi Chi cosplayers may argue the finer points of this adaptation, but it is fairly dazzling it its own overextended, futurist-teenpulp fashion, and Chow makes a vastly more entertaining Roshi than he did a King.
The New York Times by Nathan Lee
May or may not appeal to fans of the Japanese fantasy franchise it is based on, but aficionados of apocalyptic teenybopper kung fu extravaganzas are in for a real treat.
The A.V. Club by Tasha Robinson
The film is crammed with treats for old-school "Dragonball" fans, from the inclusion of all these characters (who don't actually do much) to the moment when spiky-haired Goku dons his orange gi. For everyone else, this amounts to another seen-it-before, probably-willing-to-see-it-again distraction.
