Disappointing for both atheists and theists
I'm an atheist and am inspired by both Dawkins and Krauss, but this doco was really lame. It was basically just a bunch of excerpts from their speaking engagements interspersed with scenes of audiences clapping set to music.
This was not a good film for putting across the atheist position to believers, but perhaps that wasn't its point. However it was also not entertaining (IMO) for people who are already atheists. It came across as just a lot of back-patting and self-congratulating on how smart we are to not believe in magic.
The whole thing felt like a promotional video advertising Dawkins and Krauss, but instead of going for only a couple of minutes it goes on for over an hour.
If you want to watch either of these two gentlemen with one of your theist friends then just hop over to YouTube and watch one of their many debates in full. You'll have a much deeper and interesting conversation afterwards. If instead you're an insecure atheist who wants to watch over an hour of repeated back-patting on video, then this is your ticket.
After such a long wait from production to release this was a disappointing outcome, and while I appreciate the good intentions of the director, I hope he has other career ambitions outside of film.
