I personally loved it. I thought everything about it was fantastic, from the graphics, to the art, the gameplay and especially the music. That being said I can completely understand why it sold poorly and why someone wouldn't like it. If beat-em-ups are a genre you can enjoy, chances are you'll love it.
My Games of 2011:
The Legend of Zelda: Skyward Sword
Elder Scrolls V: Skyrim
Super Mario 3D Land
Uncharted 3: Drake's Deception
