If there was ever a reason to have an "it all takes place in the same room" movie, an escape room would have been perfect. This is not the case in this movie. What ties all of these characters together? Doesn't matter. In a movie like this you gotta have more to offer than clever traps, clues, tricks, etc.... It needs good character development and an intriguing reasoning that ties them all together. I think Exam and Saw executed this entire idea better. Some things were enjoyable but too much held this back to make it really good. See the aforementioned movies instead.
