Did you really like Saw IV, V and (theoretically) VI? Well, then you’ll love The Collector, written by the same guys and presumably featuring similar amounts of booby traps.
A guy tries to rob his boss’s house, but then when he shows up some guy in a gimp mask has tied up the family and thrown bear traps everywhere. Now slightly evil guy must fight super evil guy in order to prevent him from collecting just whatever it is he collects. Maybe it’s just nice china. I’d just let him take it in that case.
Positives about the trailer? The backwards fall into the bear traps and the soundtrack. Those Saw guys know how to throw together a good soundtrack, I’ll give them that.
