I just watched the Evil Dead remake and was surprised by how good it was. With that said, I didn't have high expectations going in, but I think the creators were able to put their own spin on it. I also think it was better than the original.
Well, the one thing the original will always retain is its originality. Nothing messes with Sam Raimi's special effects either. But do consider that Bruce Campbell was a producer on the remake, so it was in good hands.
