Read part of this review from Horrorsnotdead.com that talks about the comparison to Saw:
"THE COLLECTOR may be a lot of things and may feature a house full of traps, but a SAW franchisee it ain’t. Not by a long shot. Finally an American horror movie that is brutal without being a freak show. An American horror movie that is a legitimate throw back to an era gone by without having to yuck it up. An American horror movie that tortures people without devolving into torture porn. An American horror movie made outside of a major studio umbrella that doesn’t give a shit how small its budget may be, that doesn’t have to shortcut tough logistics with insert shots and cutaways. With his debut Dunstan has proven to be a better director than a writer. He keeps his camera on a tight leash when following the action, completely abandoning every aspect of the SAW films that I hate. No spinning camera, no editing room seizures, no set direction grungier than a NYC sewer pipe. It’s a very measured take on the extreme events that ratchets tension with a build up instead of trying to snatch your attention with a sudden onslaught of gore. THE COLLECTOR is easily the best American horror film so far this year and, looking at what ‘09 still has left to offer us, I’ll be shocked if it doesn’t stay that way. "
