Yes, it could have done so much more and gone way beyond. But I don't know if that would mean "better". There were plenty of spaces for more facts, arcs, narratives and things to be explored. But I think the fact that they weren't there was by design. Actually the movie made me cry and care about the characters in the end. So I think this is "mission accomplished" isn't it. It has that straightforward cold hearted but yet gentle and beautiful touch of morality and love that Nordic war movies always seem to have. The last 30 minutes are really worth it. And pay attention to the kid, the protagonist couple's kid.
