Other than the technology, I was very disappointed in the film, which, perhaps predictably, was a post-apocalyptical dirge about how evil humans are and tells the story of how we destroyed and abandoned good old Mother Earth blah blah blah. Dumb. Instead of using this medium to uplift the audience the film leaves you feeling either angry (me) or lousy. Very, very disappointing. Skip the film here; see a concert instead.
Five stars for technology, 0 stars for content.
