It was not supposed to be just another FPS...
(if you have not, check out gamespots review)
let's make it quick then:
EPIC wins:
-beautiful graphics
-great voice acting
-imaginative weapons
-short learining curve
EPIC fails:
-boring music
-unsurprising story
-mouse acceleration
-bad support for 4:3 monitors
-problems with textures, shadows etc. on many GPUs
-hitching & stuttering on smaller resolutions
-gets repetetive
-stupid AI
-bugged multiplayer
-no jumping??? (I miss the bunny-hopping from Painkiller)
All in all as I was playing Bulletstorm I had a constant feeling of deja vu. Where have I seen this stuff...? hmm... maybe in dozens of other shooters that did all this before?
This game tries so hard to be something fresh yet it fails totally. It was an unsurprising and quite boring ride.
Save your money for something else.
EDIT
You can add to the "fails" also -long uninstalling time lol
