With that said, in my opinion Evil Dead is hands down one of the best remakes I've seen. And also the best horror film I've seen in years.
Relative newcomer Fede Alvarez takes the helm as director, but he has the blessing of both Sam Raimi and Bruce Campbell -- both of them producers of this film, with Raimi as a constant creative consultant as well. This movie is supposed to be what the original The Evil Dead would have been, if they had the budget and effects at the time.
Alvarez wisely stays as far away from CG effects as possible, relying almost completely on prosthetics and practical effects, and the result is some truly cringe-worthy, stomach-turning scenes.
I don't want to say too much about the film except that if you haven't seen the original, I would advise watching it first. Those that have seen the original will appreciate the remake that much more and will also know what to expect going into this movie (notwithstanding some sly winks such as the Michigan sweatshirt and the old car). This is a warning for those that haven't seen the original or any of the new trailers. This movie is not for the faint of heart. It's not for those that get easily queasy. It pushes its R-rating as far as it can go. There are definitely some images you cannot unsee.
Evil Dead doesn't mess with the original formula too much. It retains enough of the original flavor and also manages to have its own flair, which is highly appreciated. A few of the characters are fleshed out a bit more to make the story more believable. As in all horror stories though, you can never underappreciate the stupidity of the characters involved.
This movie is best seen with a crowd of people that will laugh, groan, and cheer along with you. If you were a fan of the original, you owe it to yourself to see the remake...If only to obtain a new meaning to the horrified exclamation: "Her eyes...what was wrong with her eyes?"
