I've read comments pointing out that this movie has ripped a lot of ideas from other movies and that there are situations that are so over the top that they get silly.

To that I say; Sure, why not? It's still entertaining.

I agree that they could have used the cast differently and that some of the plot points are quite unbelievable but on the whole it doesn't distract from the tension and the setting of the movie.

The profilers sometimes act pretty stupid and out of character but the actors do a very decent job portraying them and Renny Harlin has actually done a really good job with the directing.

If you want a horror/thriller/action flick where you keep guessing pretty much to the end and don't mind recognizing bits and pieces from other movies then this is for you.

Well worth a watch (no pun intended).
