I watched this on DVD. The first half of the movie seemed like it needed an intro as to why the world was so devastated. Also why there were no threat of violence from gangs hoarding all the resources like most other apocalypse movies? Nice human touch, but not realistic. We don't know anything about the planet except for the slice of life of a dozen people. What happened to the weather patterns? Strike one. How does the space team manage to get their hands on all the fuel needed to launch multiple rockets if there is not even enough food to feed whoever is left on earth. Strike two. The middle of the movie was the best part. Their journey was engaging and scientifically reasonable. The ending with Morse communication was snake oil and mirrors. Where did that multi-dimensional structure come from? Seemed like it came from 2001 Space Odessey. Strike three. The plot leaps from grounded science to Twilight Zone too often for me. Before the movie I was wanting to give it a high grade, but I don't think I'll even watch it again. Anne Hathaway bumps it up a notch.
