I had a fun time with bulletstorm. The locations were beautiful, the plot simple, the characters hilarious, and the gameplay extremely satisfying. 
 
I'll never get tired of kicking people onto giant cactuses EVER. 
 
But things are not perfect. It takes too long to kick people to death, Ammo can be a big problem near the beginning, and the ending was such a freaking cliffhanger!!! 
 
For all its flaws, bulletstorm is still a nice breath of air from all that grey and brown FPS shooterism. Bullet storm blows away that doldrum but for how long who knows!
