"perhaps the greatest surprise doesn’t come in the form of plot twists but from the fact that the movie is... pretty damn good. Let’s not be foolish — it doesn’t hold a candle to the first two James Cameron films, but it wipes the floor with Terminator 3. As a movie all on its own, not compared to the prior entries, it works very well."
