There's no dialogue here: this episode tells a story almost entirely through dance. This is a gift to viewers. You don't really get to see a story told through dance without specifically seeking it out, or visiting the theatre.
Unfortunately, I just didn't enjoy it.
I've been reflecting on why exactly I didn't enjoy this. Am I being closed-minded? Is this an acquired taste? Am I missing out on something beautiful?
The best conclusion I can come to is that this story in particular is just not interesting. I think you can tell an interesting story through dance. I think you can also tell a very boring story through dance. Unfortunately, I think this is a boring story -- dance or no dance.
Essentially, we just see a woman connect and grapple with her past self. It has conflict and emotion, which is something. But there's no real goal, need, danger, surprise, anticipation, or mystery. Simply put, there is little reason for the viewer to care about what happens, and that must be present for a story to be worth watching.
Those who are inclined toward the 'high art' end of things often tend to celebrate bad art because it's 'artistic'. This is an example of it. A good story could have been told this way, but this wasn't one of them.
