100% agree. I was awaiting for Netflix thread to pop-up to ask (hopefully someone who works there): Why there is no way to tell Netflix that I already watched the show and I'm not planning to rewatch it again any time soon or hide the ones I tried and decided not watch (or may be watched before)? No matter how many times you show me them I'm not going to watch...

You can still have nice features around it: separate list at the end of scroll with my old movies/shows (may be with number of times I watched it?). Once new seasons released send them all the way to to the top etc.

And I will be able to discover something new. At the moment it is cluttered with things I don't want to watch so lately I was not happy with Netflix at all.

You should see such patterns in your data.
