Yeah, that ending was underwhelming to be nice. Lots of issues with how things went down. I would have greatly enjoyed a more Ellie-centric revenge tour of just her going solo to Seattle, being a badass, hunting Abby and slowly picking off WLFs a few at a time, but specifically targeting Abby's crew. The scenes with her and Nora were some of the best of this season, I want more of that.
Using the cover of the Scars war to distract the WLF from knowing it was actually her making the kills would have been fun. They could have had flashbacks to Joel when he taught her things on how to survive, stealth and how to kill. Also could have had her string up and gut some WLF in the woods to make it look like the Scars did it to maintain her cover. It would have been interesting if her efforts lead to the WLF invasion. Lots of options if they wanted to make her a real hero-like character, filled with rage, avenging the one guy in this world who cared enough about her to save her and raise her for several years. Could have really pulled on those heartstrings with a line to Abby at the end like, "My name is Ellie Miller, you killed my father, prepare to die!"
Instead they chose melodrama with the Dina relationship, the love triangle, insanely unrealistic escapes, and a complete lack of tactical discipline and stealth, while sneaking around a heavily fortified city. Hard to get behind characters that do dumb things, have magical escapism, are caked in plot armor and don't feel like the world's rules apply to them. Too bad because this universe had a lot of great things going for it.
Overall this season:
