Good enough for what it sets to be.

Rating: 6/10 (20 October 2017)

A unique idea, akin to the Saw movies. This is a low budget psychological thriller. There is a lot of dialogue, and drags in parts. The Acting is low budget done well enough. There are good parts, and some real cringe and stupidity.
The characters are mostly likable, but there are some overly irritating scenes. Pointless arguing is a true result of high stress, however it doesn't make for an engaging movie.
We are never answered why. If you've seen any of these minimalist psychological movies, you'll understand. Very few answer any protagonist questions. This it is an endeavor into peoples behavior when they are stressed to the point of breaking. It's done well enough to be entertaining, but satisfies as much as a rice cake.
