I enjoyed the film. It's different to other horror movies I've watched.
The overall nods as to what makes a typical horror film, well, a horror film such as how the characters are influenced to behave like stereotypical horror characters, the warning by the hillbilly at the beginning, the typical setting and decisions the characters make are what really make the film.
It's a horror film, but I don't view it as seeking out to scare its audience. Instead, it pokes at the various conventions of horror films with subtle references to other horror movies at the same time.
