Yes, I watched it. I'm a big fan of Errol Morris, https://www.imdb.com/name/nm0001554/
These 3 movies are near the top of my all-time-faves-list.
"Wormwood" is a bit slow and methodical, and might seem a little tedious for some, but it makes some very worthwhile points.
I can "spoil-the-ending" for you if you'd like.
