It'd be nice to have an "I've already seen this" button that will mark an episode/season/show as watched so it doesn't keep coming back up. Netflix really wants me to watch Breaking Bad, but I've already seen it. I liked it; give me more like that, but not exactly that

That's not just nice, that is the most obvious "feature" a normal person would design. I've stopped watching Netflix because of nonsense like this. They know I've seen it before, because I watched in their player. Also, even the tiniest, most modest application of analytics would discover that I always watch one series at the time, from start till end, or whenever I'm bored with it. In the past years, I have never ever watched a thing twice. Still, it was constantly showing me things I've already seen.

The only conclusion I can draw from this is that Netflix does not have have my best interest in mind when designing their algorithms and that they don't respect their customers. So I canceled.

You can do this with YouTube. Just click "Not interested" in the three-dots menu, and click the "Tell us why" link that appears.

After which it will still recommend it to you.
