Just saw that DVD....
I rented it on netflix.com and saw it.
I watched this film for only 20 minutes then i stopped. I would not recommand this film because it's boring and too different from High Tension and The Hills Have Eyes. This film looks like mexican style. It's not horror. I also had hard time to understand this film so i gave up in 20 minutes and mail back. So...I don't recommand this film, but you can rent if want to and if you fall in love with Alexandre Aja's films.
