I keep my media organized well organized in a folder structure. I either watch it from my PC, or my TV (with Kodi).

I don't want it organized for me. I don't want to "search" for the show/movie that I want to watch. I don't like seeing the movie poster where I might only be able to fit 12 items on the screen at once, I want to be able to see 50+ items in a directory list. I don't like/want all the Database back-end stuff that gets done in plex/jellyfin (IMDB lookups, rotten tomatoes reviews, etc.)

I use Jellyfin for my kids shows. I use Kodi for my TV.

And the thing I despise the most, I dont' want to rename/restructure/reorganize 100TB of media just so JellyFin can auto-guess incorrectly the movie/tv show/season/episode.

All of the kids crap? Dumped into a single folder and Jellyfin guessed most of it. The stuff it got wrong, I don't care about.

My stuff, that's been carefully curated over years? Even if I just feed jellyFin the content 1 directory at a time, it can't get seasons/episodes straight.

I don't watch my media when I'm away from home. I don't share my media.
