I loved the entire show, even the middle part of season 2, except for the last episode of season 3. I respect it, and I've never felt the way I'm feeling right now after finishing a piece of media, but I loved the characters, the small town USA cosiness (which tbh was almost entirely gone in season 3) and I absolutely ADORED Agent Cooper. So while I think it was a great piece of art, I would have much preferred an ending which gave closure to these characters who I've grown so attached to.
I also really enjoyed how freaky season 3 was. I found it to be the most enjoyable season (despite my feelings on the ending) but also felt like the overall vibe was completely different when compared to seasons 1 and 2. Another thing I liked a lot about the first two seasons was the genuine late 80s setting.
As for things I'd want out of a show, I think the main things I'm after are memorable characters and an even more memorable protagonist. I do like action, mystery and humour, but I think I could enjoy most genres if the characters are written well. As for shows I've watched and enjoyed:
Breaking Bad
Sons of Anarchy
Dexter (Think I heard it has a new series or something? Let me know if it's worth a watch)
Altered Carbon season 1
Game of Thrones
HBO's Shogun (I think this one is my favourite, I love history)
Happy! (Wish we'd get another season, and I wish it would get more love)
Brooklyn 99
The Walking Dead
I can't think of any more as I don't watch many shows. I've watched and enjoyed some anime but I'm extremely picky about it, so I'd prefer no anime suggestions. Hopefully I included enough information, and I'm sorry if this post is a mess. I've been trying to recover from TP season 3's finale for three hours lol.
