So, like Marilou, I have now seen The Cabin in the Woods. I too enjoyed it. The gore didn't bother me. In fact, I thought they walked away from a lot of gory opportunities that other filmmakers would have embraced, but then, I've seen a lot of horror.
That is not a complaint! I like it when a movie doesn't feel it has to show every excruciating detail of someone's fake death. And this movie had enough blood to go around. I'm thinking of the elevators.
This was definitely horror of the winking variety, where there are laughs mixed in with the horror and plenty of jokes, including the end. That's how I saw it, as a departure from horror stories that's meant to make you laugh, or say, "That's so cool." They could have gone into philosophy. They began to dissect the horror movie "Cabin in the Woods" trope, but they stopped and went for the laugh instead. I think it was the better, more crowd pleasing, choice.
