America never did John Woo any favors, did it? The man who gave us “The Killer” and “Hard Boiled” now offers us a movie where American stars John Travolta and Nicolas Cage seem to be competing to see who is a worse actor. I guess when you’re working alongside Cage, though, you either have to be as awful as he is, or else risk causing some kind of black hole. Either way, for a man who has such a skill for delivering breakneck action films, “Face/Off” is that movie so moronic, you can’t even excuse it as science fiction. It’s kind of that movie you just accepted in 1997 mainly because Cage and Travolta joining forces was a little better than when Travolta met Christian Slater in “Broken Arrow.”
