I have faith in Wong, I enjoyed Kung Fu Hustle immensely. As for Bay, I loved Transformers.
I'm hoping for Dragonball to be in a similiar vein as Transformers, a fun action film a few laughs, with some tense involving sequences for the audience, with Kung Fu Aliens instead of Robot Aliens.
What I enjoyed about Transformers was its ability to be completely out of this world and fantastical without alienating the audience. I went in with some knowlegde of the Transformers and their world and thoroughly enjoyed it, my girlfriend went in with no knowledge of it and loved it. Dragonball needs to be likewise, accessible to wide audience.
