In no way did this show sell me on the "tramlines" well enough to make for a satisfying payoff. Ultimately, perhaps, it's working too hard against its medium - stories are fundamentally *about* characters making choices. So all of the hand-wringing about agency (or lack thereof) didn't come off as credible. Just banal. Regardless of how pretty the machine looks.

Apart from that, Lilly was a putrid lead character. I don't know enough about Sonoya Mizuno's work to assess her as an actress but, oof, nothing worked. Assign that blame to any combination of the acting, writing and/or direction. The story dragged, often badly, when she was involved, and I really struggled to find anything compelling or special about her character in any way. Which became increasingly suspect as the story took more and more time to have its other, better, characters deliberately point out how special she was. Please.
