Charleston City Paper
The film critic in the Charleston City Paper writes that there are moments in The Hills Have Eyes where "new heights of imbecility must be scaled" by the characters in order to keep the plot going. Not really sure what he/she means exactly, and it's a capsule review so they don't have to explain what they mean.
On of the things that make the movie (or any movie, for that matter) entertaining is that there are no great leaps of imagination. It stays within the bounds of expected human behavior. The thing about movie critiquing is that when people (especially one's friends) start to talk in glowing terms about a movie, the instinct is to pan it. The solution is to not have any friends. Works for me.
