Gets off to a good start but devolves into the shakiest, most chaotic handheld can movies I've seen. There are some good scare us along the way , but but others so calculated that I knew when they were coming., like with the little girl and the dog in the elevator. That the people were total morons didn't help their cause either - would you touch someone that looked like they spent six weeks with the Ebola virus? Jennifer Carpender looks really good in a ponytail, I wish it were her hair that way during Dexter, and gives one of the most realistic for trails of pure terror during the last half hour. That said, she's constantly screaming and really grates on the movie experience. Add in that you're almost in complete darkness during that time, and becomes a real ordeal the reach the finish line. Even so, I won't let this dissuade me from watching the Mexican original which is no doubt superior as they often are.
