You know, I've noticed some pretty heavy genre shifts. I'm not against them, but they can sometimes be quite jarring. Westworld was pretty jarring. Some less so, like Dark (which I didn't mind at all) or maybe Lost. I don't think it's inherently bad, I think it can be disappointing sometimes when you expect it to be one way and then it shifts hard.
Honestly, when Alex was revealed, I was disappointed. I really live scifi, but some tropes are tiring and overused. I'm really really really hoping this AI is actually benevolent because I'm exhausted by the malevolent super computers...
