In my opinion Netflix tries too hard to make me watch more than I care to. In particular why can't I just by default enjoy the credits of a movie or series I just finished, instead I have to quickly use my remote so Netflix doesn't try show a trailer for something else, and there is no option to turn this off.
Relatedly their tvOS app gets laggy after just tens of seconds of browsing and it's been like this for over a year, how can they not fix it?
