That button infuriates me, as it appears to do nothing except grey out the cover of the show - the show is still shown in my "currently watching", it comes up in "trending", and it's even in my "recommended" section! What was the point of even providing me the option? I suspect it might be part of an A/B test to see how many people engage with a button that does nothing. I absolutely loathe this sort of dark pattern but I have yet to convince a manager that "gathering data!" is bad thing...
