So we checked this out last night.
I thoroughly enjoyed this movie. It was a very fun romp. I would hesitate to call it a horror movie though, because it was never scary, nor did it ever attempt to be. It was almost like a cinematic thesis paper by Joss Whedon written on the horror genre that cites everything from Sam Raimi and Tobe Hooper and George Romero to ancient civilizations such as the Mayans and the Egyptians.
In that sense it is a joy to watch. However, I do feel that the jokes could have been a bit more finely tuned. A lot of it seemed to boil down to playing the clichés while telling the audience "Hey, look it's a cliché!" and then patting itself on the back. I don't think it ever really twisted them, so much as reveled in them.
Speaking of twists, the last week I've heard nothing but how "this movie has so many twists" and avoided spoilers like the plague. However, it really doesn't. There's an A storyline (kids in the woods) and a B storyline (you know what it is) that is literally revealed in the first five minutes. That's fine. I'm not against the reveal, because it led to some great comedy like when they're betting on what item the kids will pick or dancing to their music. But in the end, it's not really a twist that the two storylines converge in the third act.
Movies I spotted references to:
Texas Chainsaw Massacre (original)
Friday the 13th (both versions)
Evil Dead
Evil Dead 2
The Hills Have Eyes
The Ring
The Grudge
Hellraiser
Night of the Living Dead
The Strangers
Pan's Labyrinth
Halloween
Scream
I enjoyed the movie, but I didn't love it like some. For me, a great meta-comedy both can deconstruct a genre or subject and then build onto it to make a genre movie that is usually better than most of the movies it's satirizing. For example I love Scream, Shaun of the Dead, Hot Fuzz and Kick-Ass. This to me gets about 3/4 of the way there, but doesn't quite finish it to blow me away. As it stands, it is a fun little movie that certainly makes horror movie clichés even more fun and obvious. But it's not an all-time favorite like some of the best meta-films that I have seen.
