Cabin in the Woods - may have spoilers!!!

Has anyone seen it?  Thoughts?

I saw it last weekend.  I don't want to post spoilers, but I'm not even sure what would be considered a spoiler.  So don't read on if you can't wait to see it and know nothing about it.

I kept hearing how great this movie was, it had a mid-90's on the tomato meter, I heard references to Hitchcock and some of the classic ghost story kind of things.

I had no idea it would be...well, what it was.  If I had known that it was such a deconstruction of the genre, a satire, I probably would have loved it.  But I went in expecting it to be like I felt after The Blair Witch Project or The Others or Alien or 28 Days Later.  This wasn't that at all...

I  know the movie was made years ago, but I also think the timing REALLY sucked as it has some serious similarities to the Hunger Games (the giant dome, controlled elsewhere).

Besides, I kept waiting for Bradley Whitford to say he was going to find President Bartlett.

Anyone else?
