Ugh. Relentless torture- and gore-porn backed by an elaborate yet inept plot and dreadful dialogue. The 3D was pretty unexceptional as well: mostly flat, except for a few gore shots when they amped it up to theme-park proportions. Better than an Uwe Boll film, but only just. Score: 1 star out of 4.
