Pastiche of 70's/80's video nasties (especially reminiscent of the first half of 'I Drink Your Blood'). I felt it was sorta hollow and pointless... but you know compared to most the shitty horror genre movies floating around lately, it wasn't so bad. Which is somewhat of a relief, due to all the bad horror movies Cage has been involved with. Guess he was due an OK one.
And not sure what all the arthouse/fantasy shit was aiming at, seemed tacked in to make it seem edgy and stop the hipsters walking out the cinema/switching off their laptops.
