Where were they going?
The plot has absolute zero context and this bothered me a lot. Also, what a strange combination of people to throw together. I only got from the beginning that they were supposed to travel some more distance and that the crash-landing was on a different planet than the one they were supposed to go. This makes it even more absurd that it happens to be with a breathable atmosphere and that they landed within walking distance to what seemed to be a human settlement, no less.
Oh well. At least the second half was much better, and I still enjoyed the movie. 6/10
