Saw this today and enjoyed it. Definitely more a science-y movie than anything else, not at all a horror or scifi/action movie. Worth watching at home since they do a lot of 3 or 6 multiscreen shots and its nice pausing in some of them to catch stuff. Its pretty straightforward, no over the top stuff or even any character development, just a story of what it might be like for man to go exploring beyond our planet. The non-linear story/editing made it a little frustrating at the beginning but it kinda worked.
imo its something you would like if you watch a lot of Nova, Universe, Cosmos, etc. The launch stuff also made me itch to go play Kerbal!
