A footnote. An enjoyable one to be sure, but any power this has feels borrowed from the series itself, directly proportional to how long it's been since you watched it. I can't imagine viewing this directly after finishing the series for the first time.
There's some interesting stuff in the margins about goofy thwarted masculinity and men Having Feelings that ultimately gets undone by Western bravado. Distance is what makes this thing, for better and worse.
For me, at least, it's been long enough.
(Though not so long that I didn't clock the bald cap right away.)
