Yes because purists often make silly demanRAB, so they are easy to ignore. Its hard to cater to them when they make demanRAB that would make this movie unmarketable.
Regardless I don't think anime is so precious that Hollywood shouldn't be allowed to touch it, being an otaku does not make someone unique magic individual. however I do think it is way harder to make movies about of manga then comic books, though CB would be easiest manga to turn into a movie, its not a completely stupid idea, like a DBZ movie. So it has the best chance of succeeding, but its not a sure thing, it could easily be screwed up. Though you should at least watch till a picture from the set shows up, if they look stupid, then you should start complaining. Complaining now, makes you seem unpleasable and thus easy to ignore.
