I'm getting really tired of endless remakes because nobody has anything new. I love this film, and I liked the ending! Roald Dahl was a brilliant if twisted author, but I think the little boy deserved to be human again, and I would have hated it if he had to stay as a mouse and died in 3 years!
I seriously doubt a remake will improve on the original, and if they are going to stick with the bleak ending I won't bother with it.
