Gameplay:
Take the already perfect formula of the first Viewtiful Joe, add the ability to switch between Joe and Silvia, mix in some new moves, and add the Six Machine as a weapon and you get Viewtiful Joe 2. The gameplay is the same, with new stuff, making it better than ever before.
Graphics:
The same style as the first. Hasn't gotten any better, and it hasn't gotten any worse.
Sound:
Great music, SFX, and voice acting yet again.
Replay:
As with the first game, there are unlockable characters and difficulties that will make you want to play through this one again and again.
Overall:
Viewtiful Joe 2 is a better game than the original. It may not have that awe and shock sensation, but the formula is the same with improved gameplay elements. BUY IT!
