Considering that this isn't a big budget thriller, it is actually quite good. Plenty of intense moments where you are kept guessing. Plenty of suspense when you can't be sure who is who and what is what. The ending is a tad anticlimactic, but maybe a bit more realistic than what is usually shown in this kind of film. Although there are no big names in the film, the acting is also quite good. I say, it deserves a thumbs up for this one.
