Some years ago I hit a point where I stopped trying to seriously second-guess twists and just let myself be taken by the story, as I realised I enjoy it more that way. I think watching Inside No. 9 helped.
I still think it's fun to speculate, but putting lots of energy into trying to work out for sure what is going on in a 'twist' story feels like a route to likely disappointment: either you put it all together and get it right (in which case, well done you! you're clever enough that you spoiled the surprise for yourself!) or get it wrong (and end up irritated with the story for going in the 'wrong' direction).
There are those occasional stories that are smart and play on viewers' tendency to second-guess twists by deliberately leading them down a certain path only to pull a bait-and-switch, but it's hard to do that well and in a way that makes sense (again, a couple of episodes of Inside No. 9 spring to mind, like 'Tom and Gerri').
These days I prefer to be taken by the story without trying too hard to work out where it's all going.
