Really liked it, the trailer is so revealing, that there wasn't much left to reveal, besides a few minor details. When the brother started talking MMA and genetics, I knew what the overall plan was. As an empathetic horror/thriller/suspense fan, I wish it was a little sharper, and played a little more straight, a little more tense, for most of the film's acts. The deer scene was great, as was the cold open, and the opening moments with the parents, which were all covered in the trailer, which isn't the movie's fault......"how long has this....this....thang....been going on?" I do think it could a little too broad and near parody, stepping over from satire, in the last half, but I throughly enjoyed it nonetheless.
*I thought Rod's character got a little too close to stereotypes, more then once. Maybe on purpose?
* A lot of scenes seemed cut from the trailers
*One of the 'twists' wasn't surprising, mostly due to the trailer, again, and some of the information given to the viewer.
