Movie goes faster but downhill from there. They escape....other stuff,.... a lot of quiet time in this movie, some interesting survival stuff goin on, more quiet, then finally the end. I had trouble figuring out what the deal was with him always wanting to be away from other people. The movie never explained that. I think the daughter never understood it, either. So that was frustrating, but the environments they end up in are very real, and there was never a time when I gave up on it. I'd give it a grade of 6 on a scale of 10.  I think I would have written the story to tell more of the story.
