By almost all measures, The Collection isn’t a movie that should exist. A sequel to the lightly regarded The Collector, a film cobbled together of an unused Saw script. The original hit at the tail end of horror’s extreme torture phase, and it came and went without much fanfare. Yet director Marcus Dunstan and his co-writer Patrick Melton returned for a second go-round. What’s more surprising than the fact the The Collection, now out on DVD/Blu-Ray/VOD exists at all is that it’s a pretty damn entertaining film.
