I am not too sure about the Bleach movie, but it might be entertaining. With any property like that, whether it's based on a comic book or an anime or anything, there's a good chance it'll fail, but I think it's worth it to wait and see what happens! ^^ I think that the Ghost in the Shell one especially could be cool, since the same screenwriter that had Shutter Island is currently attached to the project.
When the trailers come out, though, then it's a different story. XD There are two big fighting game movies coming out this year, and while Tekken's movie at least had a costume designer who took the time to look at screenshots from the game, but I'm afraid that if I got started on the King of Fighters movie, my soap box would keep getting bigger and bigger until I fell into it. Those are game movies rather than anime ones, though, so it's a bit off topic. ^^;
