I was in two minds about that, whether they were just milking a premise in the hope some direction towards an ending might strike them at some point, or, whether they suffered from what many such shows tend to suffer from (particularly netflix ones), which i'd call renewal syndrome. Which to me is when just over half way through a season, they find out they've been renewed, and it feels like all of a sudden they have to stretch out storeylines and save things that were seemingly going somewhere for the following seasons.
Basing it on S1 alone, nothing feels like there is any intent behind it. But i take on board that maybe it comes together over the 3 seasons. But the way it went, certain early characters just dropping off a cliff and being forgotten about, or other seemingly significant characters only suddenly being introduced in the last and penultimate episode, similarly some previously never hinted at themes suddenly emerging at the end, makes me think they have been scrambling for a story all along. Somewhat feels like they are relying on the perseverance of the viewer hooked in on a bit of a mystery and (annoyingly overused) repeating sound effects.
I think I probably Do need to stick with it till the end now to hopefully prove myself wrong.
Imho, series like this need two things to work. The story needs to have a holistic beginning and end, and everything needs to at the very least feel like it has always been intended and pre planned. And two, the reveal needs to be good, some let the viewer gradually work it out for themselves (nolan does that best), others rely on a big sudden mouth wide open reveal, that you can then look back at and see existed all along. These set ups live and die by their ending. (why imho s2 and s3 of westworld fail spectacularly)
S1, for me has none of the above. Hence the question whether it does over the full run. It is actually incredibly frustrating the way it ended, and if i had to wait for another season to come out as opposed to being able to binge it, no chance would i continue with it. But i probably will.
