I read that the main reason for this remake was to reimagine Wes Craven's vision using updated technology. While there are updated effects, it doesn't really add to Craven's original movie whatsoever.
That said, the acting is fairly strong (having the likes of Rooney Mara, Connie Britton, and Jackie Earle Haley will do that), and the film does manage to capture a dark, creepy tone that has been missing since... oh Dream Warriors?
Other than the 'return to scary Freddy,' this movie's existence can't really be justified. I suppose I should just be thankful Platinum Dunes didn't fuck it up on the same level as Friday the 13th.
