Impressions before seeing it
I didn't know much about this movie, which was good, but I had an impression that it would have that mysterious Saw thing going on. Plus I found it in a bargain bin for four dollars. Score!

How was it?
Yes, it was like Saw, at least for the first bit anyway. A bunch of guys waking up in a warehouse with no memory, that kind of thing. I love that kind of concept, strangers working together to figure out their identities and how to escape their predicament, so for me it was incredibly fascinating and satisfying. My problem, though, is that there were too many plot twists at the end (don't worry, I'm not going to say what they were). I think there were about three, and the first two were fine with me, but then the final one seemed excessive and put there just so that the filmmakers could say "Haha, gotcha one more time, wasn't that fun?" No, it wasn't, I want the first 80 minutes of the movie back.

Recommendation
I think it's definitely watchable for fans of stuff like Saw and Cube, because it is totally that type of movie, and quite enjoyable even if you're not a fan of the ending.
