Even that is a bit too much to my taste. For self-promotion pre-roll kind of ads, if I can skip it the first time I see it, and I don’t see it ever again, and I don’t see more than one ad like this per day per series, then I’m reluctantly okay with that.
But ideally, just stick to some non-video recommendation UI during the credits, and let me discover things on your platform by myself otherwise, and don’t get in my way when I’m trying to enjoy the show.
