I give this film four stars. I usually don't like movies that make me tense and afraid anymore, but this is a good one. I was on the edge of my seat the whole time. There were no lulls or boring lapses. Similar to the Bourne movies, the suspense maintains a steady pace and the action is non-stop. Liam Neeson is awesome.
I highly recommend renting this one if you haven't see it already.
