Nothing but bleak, one-note depressing scenes - punctuated by extreme violence.

I was immediately reminded of the film "Kick-ass" (which I just couldn't finish).

Too much goes unexplained, too little is done to make you care about what happens to the characters, and nothing is really done to set up the expectation/anticipation of the "next generation" mutants.

Yep, it's not your standard super-hero action flick - but this treatment doesn't make it any more watchable.

Spare yourself the agony and tune in to a medical video of someone's hip replacement surgery; all the blood, gore and violence - with a positive purpose.
