Killzone 2 Demo - First Impressions!

Just finished playing the Killzone 2 demo - first impressions:- Graphics are very well done; lots of stuff happening in the background, lots of explosions, particle effects, smoke, etc. 'Cinematic' is the best word to describe it. It's the first word in my mind the moment you step off into the world of the game.- Gameplay seems okay; perhaps it would be better if I had a Dual shock controller.
