I gotta say, nick seems right about this. The gametrailers review actually makes this game seem like something I'd want to play. They point out what they don't like about it, but they also say how it can be fun sometimes, which some of the gunfights look like they can be. The gamespot review shows only bad footage of the game. One clip of a guy stuck to a wall and another clip of presumably the reviewer flailing the gun around, which looks extremely exaggerated when you watch the other review, where the guy can easily control his movement. I really didn't think the graphics looked that bad either in some places.
I mean, I'm sure the game isn't amazing, but I don't think gspot gave it a fair shake. I don't think they gave any of the Wii games a fair shake. Of course, I haven't played Wii yet, but from what it looks like it seems to be true.
