Since it was by the same writers as The Departed, and if you've seen it, you know the end already. However, this movie was improbable in how one man takes down an entire nuclear research facility, but with enough probability, somewhat, to be compared with the first Die Hard. This movie was cheesy with the scenes of his dead daughter and a lot of scenes were predictable. However, if you found The Departed good, you'll like this one too. Great acting on Gibson's part, enough action-packed drama to get you involved in the movie, and very very good fight scenes and shoot-outs. This movie is definitely worth seeing.
