Fun as hell if you're in to it.
Firstly the stop to shoot; most shooters let you shoot as you move, but this one doesn't, you have to stop, aim, then fire which I suppose may be more realistic, but is irritating, and besides, they have zombies! So despite the fact that some people may like that feature, I certainly do NOT. Which leads me to my next point:
If you don't like Resident Evil you probably won't like this; It hasn't got a very exciting story line, and it isn't "revolutionary" in the game play (I've realized this because several friends commented it to me).
Since this is a personal review however, I'm going to conclude that it is a fun game, with interesting challenges, top notch graphics and little to no bugs, however it does suffer a bit of a downfall due to the short story line and it's controls with "stop to aim and then shoot" (ARGGHH).
