I was pleasantly surprised when I watched this one. It wasn't a movie that tried to be more than it was, it was just a fun time. If you've watched Deathgasm or Cabin In The Woods then think of that kind of feeling when you watch this.
The dialogue between the characters (who were supposed to be like, 14), felt honestly really realistic. I know a lot of people felt like it was too clunky, but I for sure know a lot of people who talk just like that, so it didn't bug me.
The story is about what you'd expect too, so once the movie gets going you really know what's going to happen. Still fun though, I'd watch it again.
