Some tips when watching this movie:

DO NOT see it in some back alley theater in New Orleans
DO NOT watch it in an empty theater by yourself
DO NOT watch it when you're on a business trip by yourself
DO NOT see it when there's a chance you'll be staying in a creepy run-down hotel by yourself
DO NOT see it when there's any chance that the window in your hotel room will fog up at night, revealing dozens of creepy children's faces…prints left there from visitors past.

Heed my warning! I broke all of these rules when I saw the movie and I swear it traumatized me…

Otherwise, I think the movie was excellent! In fact, I just bought it tonight.
