A slasher thriller that follows a formulaic plot, this is brought to life by brave plotting, great direction, and a brilliant turn by Luke Evans.
I'm not giving anything away that's not broadcast loud and clear in the trailer, so No Spoilers:
In a great twist on the usual 'gang of criminals kidnap a wealthy couple a torture them' storyline, a gang who have just brutally screwed up the robbery they'd planned think their luck has turned when a couple arrive at their local diner. However once they make their move and kidnap the couple, they realise their terrible mistake.
There's a girl locked in the couple's trunk, screaming for them to 'make sure he's dead', and it turns out that Luke Evan's mild mannered character may be far more dangerous than the lot of them...
The movie is brilliant fun once it 'hits the fan', and Evans' character is thankfully given tremendous moments, including a lot of unexpected emotional depth and layering that makes him far more complex and interesting than the usual movie psycho.
Many of the other characters are shallow-ish cyphers, but once the action starts you really won't care much, and the violence and big set-pieces are choreographed so well that it's a joy to watch.
A fantastic slasher with funny, wry dialogue, tension built in spades, and sudden, harsh violence.
