The launch trailer for Capcom's Bionic Commando does an amazing job of making me forget anything negative I've said about the game in the past.
I've had issues with the controls in the past, and the multiplayer demo wasn't exactly thrilling, but put together a swinging montage set to some powerful music and I'm suddenly all excited that the game is coming out next week. The piano rendition of the stage one music from the original game at the end completely sealed the deal for me. Classy!
