I like challenges like the Seattle Public Library's summer book bingo, or re-reading all the Discworld books in a logical order. What's something I could do along those lines, but for TV? Not necessarily "Watch every episode of (this particular series)" but something more complex?
I'm in the US and have or can get all the usual streaming services. Any language is fine so long as it has English subtitles, but the preference is English or Japanese. At the end I'd like to feel like I accomplished or learned something, but being entertained along the way is the most important aspect.
