This was a beautiful film. For the 1st couple of minutes or so, I wasn't sure I was going to enjoy it - I was anticipating being a little bored. But that fear soon dissipated and I found myself completely absorbed. This movie manages to be exceptionally moving without ever being manipulative or hokey. Grounded, real, and inspiring. I'd highly recommend viewing on a big screen if possible since the shots of the scenery are beautiful. But it's not absolutely critical, since the stories of the wounded vets would come across on any screen.
I was fortunate enough to attend a screening where we learned some of the "what they're doing now" stories of the men profiled in the film, and I only wish that these updates could somehow be incorporated into the movie itself. (Not realistic of course, since even if the most recent updates were added today, life goes on and they couldn't stay current. But I think audiences will find themselves curious to know what these brave folks are up to.)
One thing I think makes this movie special is that despite its subject matter, it doesn't seem to have a political agenda--should appeal to those who enjoy human interest stories, regardless of their politics. If you happen to love nature, fishing, or a particular vet, probably so much the better, but I don't think it's necessary.
