When I watch a movie I start to see which actors are in it, and which of them have I seen in movies or TV shows I have already watched before.
The problem is that if I have not completely finished the TV show, then it is not a “watched” item.
So if I saw the actor in 30% of the TV show, I wouldn’t notice it on the “Watched” section of the actor. I’d like to know if it’s partly watched, or maybe check if the actor is in the episodes I already watched.
This is a good point, for instance if I pull up Charlie Cox and filter by what I have watched Daredevil does not show up as I have not gotten around to finishing yet. But it is clearly a role that I have watched him in.
