An extremely well-made movie. Don't listen to the haters.

Rating: 8/10 (5 April 2010)

I can remember back months before this movie came out, watching the teaser trailer for this film for the first time. The sense of foreboding and mystery I felt watching the trailer was the same as when I watched the film in the theater. It is an excellently-made movie.
Although it starts off a little slow (with introducing the characters and their relationships), when the action kicks in, it doesn't stop. There are maybe 6-7 minutes where there is not some kind of thrilling event happening. The relationship between the characters Rob and Beth is palpable, as is the chemistry between all the actors.
Pros: -Many thrills -Surprisingly good acting for a 'no-name' cast -Great story -Convincing special effects
Cons: -The shaky camera may be nauseating to some people -The acting in some scenes could be a little better -If you are someone who likes for all the loose ends to be tied up at the end, this is not for you
Overall, I give this movie 8 out of 10 stars. I love it, and it is in my top 10 favorite movies. It always will be. I highly recommend watching this on a large screen, with the sound turned up loud for maximum enjoyment.
