Yeah I wish Netflix separated "movies that I already watched but maybe will watch again sometime" from "movies I didn't watch yet but want to". And also from "series that I'd want to watch the new season for but don't want in my list until that happens since I am not going to re-watch old seasons".

They are almost there but looks like either my watch-flow is somehow weird or they didn't pay attention to how people actually watch things.

It might seem unlikely to you, but I would be surprised if it wasn't the most common action. Many people will watch the same thing over and over.

To that end, training the model in their users, it would not surprise me to have that be an emergent recommendation.

Yes, I wish Netflix would hide things I’ve watched more. Obviously if it’s still in My List it should remain, having a Watch it Again section is fine but they should basically disappear from New Releases or lists based on what I liked and be at the end of the list in genre categories.
