I can’t say much about this movie except, go see it in the theater. It is funny, scary and introspective about the whole horror genre. I saw the trailer and I decided to skip it initially but it got good reviews and I remember that Joss Whedon (Buffy the Vampire Slayer, and soon opening The Avengers movie) so I change my mind.
Don’t be turned off by the trailer because it is generic and doesn’t due to movie justice. The trailers tell you a bit about what happens in the movie, but it is interesting how those events come about.
