I was really really disappointed with Bulletstorm. I was expecting (from what I read) a game similar to Borderlands, and it pales in comparison. It had its moments of humor, but it's a poor Painkiller clone on rails. Really didn't care for the gameplay, lack of weapons, various mechanics etc. It was more like playing a ride at disney land than a computer game. Very forgettable title.

Borderlands has 10X more to offer.

Edit: The remote control dinosaur was a neat idea
