Yeah, so as a guy who runs a personal media server, I like how American Horror Story did it. I don't own that series, but if I did, I'd be able to name the seasons. So the first one was later named something like "Death House," but at first it was just AHS. And I think it was a play on the Amityville House movies? Second season was Asylum and beyond that... I dunno. I watched a couple, but not all of them. I think Hotel was the first one I missed, and I regret that. Maybe I'll go back sometime.

With the filenames it was always just "American Horror Story S0xEyz Episode Title", where x was the season number and yz was the episode number.

With Interview With the Vampire, The TVDB (Plex's metadata source) is still calling it all "Interview With the Vampire", so season 3 episodes are still "Interview With the Vampire S03E01 Whatever the Title Is.mkv". But on Plex, you go into Interview With the Vampire and you have "Interview With the Vampire", "Interview With the Vampire, Part II", and "The Vampire Lestat". And of course each season has a matching cover with the text in the same place. It's all really neat.

There are some anime series that do something similar.

Some people online debate what should be called what... but if it's on my media server, The TVDB has the last word, because otherwise, shit doesn't display correctly.
