I thought that final episode K.A.O. was the worst of the series.
It was definitely quite poor. Well, very poor.
While I had my complaints against last week's episode, I thought the main part of it was rather good in its depiction of a newcomer (a fish out of water introduced into a manipulative society where the usual social pressures to conform are even stronger than we have in our parts of the world) being played to achieve a specific goal.
This week's effort was all over the place. In terms of the story itself.... Some of the time, it seemed to be playing with the idea that the main character was being singled out** in terms of what messages he saw. But given that he was not the first to act on those messages, that didn't seem to be the case. (Unlike with last week's plot, I would have liked this to be at least partially explained, because it wasn't at all clear.)
The world being depicted didn't make a lot of sense. People drive around in old cars when free new ones are available...? Yeah, right.... If there are a handful of "token" workers, what is everyone else doing? How do they pay for all the stuff being agressively advertised in every room of their homes? A few hints might have been helpful (or, if they were there, made a bit more obvious).
I daresay there might have been the germ of an intriguing idea in there somewhere (perhaps it's in the PKD original, but I haven't read that, so don't know), but if it existed, it was buried under so much dross that I expect it died early on in the production.
** - So it was like last week's episode, but in a completely different situation. In last week's episode, there was a reason the target was selected... and only when the target put themselves on the radar. This week, was there anything special at all about the target? Was his reaction to irritating adverts stronger than anyone else's. (Answer: only if the rest of the population of MexUsCan is drugged with sedatives.) I could imagine that a scenario where the MC was aware of subliminal messages when others were not might have worked (if we'd be shown that this was the case). But enormous billboards with people (real or otherwise) hanging off them with a noose around their necks is not exactly my idea of subliminal messaging.
