There are dozens out to be found already. I procured it today after reading this thread.
It's gruesome I suppose. It's disturbing as a concept, but I feel that the movie as a whole fell flat. There's just not enough development of... anything. The plot makes very little progress. I found the concept more revolting before viewing the film. The film didn't make me as uneasy as I'd expected it to.
I'm curious as to how they will approach a sequel given the events of the first film.
I also thought of Teeth when I first heard about this film, but Teeth was a far better movie than this. There is character interaction and development and more of an overall plot to Teeth.
