a little difficult to follow as the timeline jumps back and forth a few times. In addition, one scene has a team member doing things here own way despite the rest of the group disagreeing. You have to watch the digital clock on the ship to realize they have stepped back in time.
Despite this, I really enjoyed this movie. Nothing airy-fairy about it at all. Lots of anxiety-ridden scenes unlike the Martian and other recent space exploration movies. Perhaps, just perhaps, this movie will give the Mars One some food for thought.
9 out of 10 for me although I know I am in the minority.
