It's okay, but there's not a lot of substance here
I think every celebrity or notable name other than Dawkins and Krauss that participates in this movie has one clip, and that's it. There's a lot more in the special features but in the movie itself, virtually nothing from them. There isn't even a lot of substance from Dawkins or Krauss. I am not an atheist, but like to get insight into other world views, and found this utterly lacking. It's watchable, and it's short, but I just kept waiting for substance, and it never came. I'd much rather watch either one of them in a debate. I find them both annoying in that forum, but they have a lot more to say, so you get much more out of it.
