I streamed this off Netflix last night. Overall, a better than average thriller--as it's nice to see more dialogue driven attempts at "thrills" rather than action. Though I think the film should have stayed as such and there were things that didn't seem believable. Also, there were some holes in the plot that didn't make complete sense and some of the situations seemed a bit over the top.
This reminds me of the earlier and better film Cube. Exam is not a bad way to pass the time if you're just looking for something to watch. So my verdict is better than your average thriller, entertaining to watch, just not as great writing as it could have been.
