Wow! This is one of those movies where it seems more appropriate to call it a 'flick' rather than a 'movie', if that makes any sense. Like most thrillers, it's great when it's putting characters in situations and making them figure out how to get out of them without showing their hands, and starts to fall apart a little once all of the cards are on the table and it gets a little more action-y.
It's exactly what it says…
