TV again - endings

 
I was thinking again how much I loved the ending of the show The Outpost and how my initial thought was something like "This is one of the few shows that gets a good ending! Most of the shows I love have a meh ending. So I love The Outpost all the more." Then I decided to go through the recent list I made of my favorite shows.

Which ones have a satisfying conclusion? Of course 'satisfying' doesn't mean 'happy'. In Spartacus, most characters except for one of my OTPs die. 

Satisfying conclusions (conclusions that felt like a solid tribute to the show and its characters):
- Spartacus
- Brooklyn 99
- The Outpost
- Agents of SHIELD (mostly, though I still have some quibbles)
- Also, shows I'm not as into, like She-ra and 12 Monkeys
- And we won't know for another 3 weeks, but I am confident that The Expanse will be on the list when it wraps

Slapdash, poor, GoT conclusions:
- The 100

That's it? Of all my favorite shows, this is the only one that had a sloppy ending that didn't feel true to the characters. So....I guess I've just been lucky with the shows I like? Or bad endings aren't as prevalent as I think they are?
