We turned this on, on a whim. We were not expecting much - I actually told my wife to give this a chance for 5 minutes and if it doesn't draw us in we'll switch to something else. But it did suck us in. Super interesting concept - I can't say too much without spoilers though. The punishment one of the characters received at the end of the movie got me pondering things like that for a while - I couldn't shake it. It was incredibly cruel - I think.
