Underrated film on IMDb

Don't get me wrong, the first half of the film was just too slow. Too many scenes of just snow and desolation. They should have edited a lot of that out.
It would have been a much stronger film if they had spent more time exploring some of the relationships among the people in the colony - we really never got to see more than a half dozen of them or what their backstories were or what life in the bunker was like for them.

That said, I think it deserves more a 6 or 6.5 average score.
