This is a must-see and one of the best documentaries - and films - of this year.

While it doesn't offer any answers, it both thrills and makes you think.

I think this is a new genre that they're all sort of working their way through it and haven't got all the kinks worked out yet but it's a genre that works for me.

I didn’t really have many expectations going into the movie (good or bad), but I actually really enjoyed it. I really liked the characters and the banter between them.
