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...
True, it does affect their recommendations but still the inherent purpose of a thumbs down is to tell them I watched it but didn't like. I would love for them to provide a "not interested" option as well.
Edit: I continue to have hope that some higher-ups from Netflix are reading these comments, and someday will create a GUI for "pros" and a GUI for everyone else (as it is now), where the "pro" version allows at least some level of customization beyond this dark-pattern insanity.
YT "not interested" is similar but worse, forgets your dislikes after few days.
