The Magnificent Seven is a pretty kick-___ remake of The Seven Samurai.
Mr. Deeds wasn't really a bad movie, but it definitely didn't live up to the original.
The Fly is a fantastic movie (I first saw it when I was 6 years old, so it also has a lot of nostalgia for me)
The Thing was actually meant as a half-remake, half-sequal--the original had them freeze the alien in the block of ice that they bring back to the base. If I had to pick one, this encapsulates all that a great horror movie should be.
The Italian Job was a pretty good remake. It definitely maintained the classic feel of a heist movie, and Edward Norton never fails.
Mark Wahlberg does, though.
There's a new Nightmare on Elm Street coming up; I have really good feelings about it. They went against using Robert Englund, the classic Freddy, and are bringing in Jackie Earle Haley (better known as The Watchmen's Rorschach). I don't think he'll let the franchise or fans of the original down. The writers (one of them wrote the Cape Fear remake, the other is/has writing/written a prequel for The Thing) seem like solid picks. The director directed the video for Smells Like Teen Spirit, and has probably 50 other music videos to his name. He hasn't ever directed a feature film though.
(ooh, that was...wordy.)
