[Movie] Best Comic to Movie Transition

This might be off the subject a little bit, but has anyone seen the "Nana" movie? It is adapted from the Nana manga. I think that is totally like the manga. The character even look and dress just like in the manga. Plus, one of the characters in the manga is a singer in a band and they got like one of the number one j-pop singers in Japan to play that part. Pretty much ANY Japanese movie adaption is dead-on. It only seems to be the American movies that seem to stray from the comics. I guess the directors want to give the comic their own brand of "flavor". That's why it is such a rare occurance when an American comic-movie is faithful to the comic.

Although, Sin City REALLY was dead-on!

Jam it back in, in the dark.
