You should be able to play a video that’s at 100% even if the torrent isn’t complete.

It could be a codec issue? If you’re using windows there’s a tool called MediaInfo you can install that’ll analyze a video file and tell you if it’s corrupt and what codecs it uses.

GoodReads is good for this. They have lots of curated lists and popular top 100 lists you can browse through, and you see the cover and a paragraph synopsis of each book.

Beside each book there’s a button to add it to your Want to Read list. Pick books that sound appealing until you’ve built up a decent list.

Then if you don’t feel like manually sourcing them all one at a time from LibGen or Anna’s, you can set up Readarr to automatically sync your Want to Read list and it’ll auto acquire them. If you’re already using automation apps like Sonarr and Radarr it’s exactly the same thing.
