Wrong Turn: derivative, nasty, effective. Same goes for Joe Lynch’s sick-puppy sequel, a spectacularly gory survivalist horror that’s as playful as it is visceral. Opening with a woman being vertically axed in half, it tracks stock characters as they encounter backward hicks in the backwoods while contesting a reality TV show. Unusually, the action takes place in daylight – all the better to see the red stuff.
