The best actor in this movie and most rational character was the dog. You would never know by watching this movie that Jim Caveizel is an established actor. There is no real logic as to why the couple decided to stay and camp except for the Peters' stupidity. I would not call this a movie where nature strikes back, I would call it a movie where a moron angry at his wife makes a lot of boneheaded decisions. Nothing about the other campers is explained. All we know about them is that the parents seem to quarrel. So is this nature striking back at unhappy couples, or people that disrespect nature. The explanation of what this movie is about really stretches logic. The only parts of it that ring true are that there are people and they are out in nature. I found this movie extremely boring and a grand waste of time.
