I was on the edge of my seat for the majority of the movie, and that is great. But the one glaring problem I have with this movie, and others of its ilk, is that I feel it has very little replay value. It's greatest attribute is its mystery aspect, which is lost once the story has unfolded. John Cho puts in a decent, MILF-less chanting performance and the movie is has an interesting presentation, of which a lot takes place through navigating a Windows operating system and footage from cameras on multiple devices such as laptop, mobile phones and security cameras.

This movie makes for a great one-time viewing, and while I can see myself watching it again, I just know it won't be as special the second time around. There won't be anything keeping me on the edge of my seat the second time around.
