"Monster Camp"

There was another movie almost exactly like this a few years back that was really intriguing, but I can't remember the title. All I remember is a quote from the trailer where a girl was explaining why she did this. She said "At work, my boss tells me what to do; at home, my mom tells me what to do. Out here, I do what I want."

This stuff is fascinating, especially because (if you watch their interactions) they have the same types of drama that any sorority would have, or any other subculture/group. It's all just humans making communities and interacting with each other, just in different styles. Interesting.
