I like it. Some of the missions can be pretty lame depending on the objectives but when you get to mow down hundreds and hundreds of beasties it's wonderful. It also looks great, and the dialogue is so bad that it's utterly hilarious
I rented/beat it and I found it to be a pretty good game. It has too little emphasis on the all out war type missions and too much emphasis on the "alternative" missions though. It could have been better than Devil May Cry had they fixed the controls a bit and allowed you to combo between your guns and sword(and air combos too). Sadly, they didn't, but it's still fun.
