You can say that all games of the survival horror genre like RE are boring. They're just methodical, requiring you to take things easy and cover every corner of the room. Different strokes for different folks.
I think Dead Space is one of the best games this generation personally. People say it didn't do anything new? What about the awesome zero-g gravity sequences? Tell me a game that did it so well and seamlessly before. What about the dismembering of the limbs? What about the spiffy, holographic UI?
There's many good things about Dead Space, and for a first iteration, Visceral Games pretty much nailed it, which should be impressive in its own right.
The love GAF gives to Dead Space is well deserved.
