This is the first documentary sequel I've ever seen. Brothers at War (2009) escaped my notice, but this one has a much higher IMDb rating, albeit with few votes yet. When I happened to be very close to the theater, I picked this viewing partly for a convenient start time and partly because someone I trust had endorsed it.
Director Jake Rademacher has surprisingly many literal brothers who served in Iraq and Afghanistan. Here he pays visits to them and some veteran friends, including women, to see how they're doing. (None of my sources name them all.) Some are doing quite well; others are struggling on at least one front. They all know soldiers who died either in battle or later by suicide.
