Fantastic to have one last chance to visit these wonderfully rendered characters, listen to the language and lines, and get a feel for the time period again.
An amazing job to get them all back together again and carry on like nothing had passed, except time, and it is not lost on us what a privilege and major feat it was to make that happen, although it shouldn't have been so in the first place, thank you to all involved who pushed this through, diverting budget from another hollow reality show with no meaning, into something of artistic merit, which this most certainly is.
To the actual movie/episode; the story was almost secondary to giving the characters some forward movement, and closure, to see how they had carried on with their lives, learned to live with each other etc etc, and the plot did feel kind of secondary to that, ie baddie did something bad, and is found out, case closed etc.
Seeing Swearingen age and Succumb to life was a core feature of this episode, but there was so much to fit into such a small space, but so thankful they did. It should be more, why isn't it?
