ah i dunno about that >_>;
Live action movies based on animes/games/etc rarely turn out good.
-points to DBZ, Death Note, Street Fighter, Mortal Kombat, Avatar Airbender-
soo im sure they will find a way to screw it up, horribly.
I think its best left to keep it as an anime, so it can push the limits when it comes to making the movie, changes arent always good, and the fans will always be fans, and will criticize harshly.
Especially if they get like one detail wrong. lol
It would just be an overdone CGI project, with like one to five human characters acting in front of a green screen.
