In gently intense but over-long & relentlessly downbeat drama "Mending The Line" PTSD suffering US Marine Sinqua Walls is sent for physical & mental recuperation to a Montana VA facility where he meets same-age volunteer Perry Mattfeld (with her own issues) & grumpy older Vietnam vet Marine Brian Cox (who ALSO has post-traumatic issues). Through fly-fishing Cox introduces Walls to a way to try coping and possibly look forward. Director Joshua Caldwell & writer Stephen Camelio do a solid, noble & respectful job, but over two hours of grief & trauma still is a tough watch. It's classy & very well performed (esp Mattfeld, Walls & Cox) but won't be for all.
