I think this is a perfect idea for a Youtube channel. Maybe in Alt Shift X's style. Just go through popular shows (ongoing or finished) and recap the big ongoing plot lines, characters, relationships, etc. One at the end of each season, maybe even one at the end of the series just for the sake of completion.

I saw a recap like this for the show Dark and, well, I was still lost through most of it, but it's a good idea. That show's a bad example.
