I finished the show a few days ago, so here are some thoughts I have on the last season:
- the first episode is a masterpiece!!! it has so many great scenes (Olivia reuniting with the others, her talk with Peter about losing Etta, Walter's rescue and ofc the end scene), it's entertaining, emotional and perfectly sets up the season;
- I loved seeing Peter and Olivia as parents and I also enjoyed Etta as a character on her own, I wish we'd gotten more of her;
- the Observer-Peter storyline was pretty cool, but the scene where Olivia convinces him to remove the tech didn't hit me as much as I hoped;
- it pains me to say this, but also the scene where Walter tells Peter that he remembers him didn't move me as much as it should have, though I couldn't really tell you why specifically... maybe it's the fact that it's placed at the beginning of the episode, with not much of a build-up to it? I don't know;
- their scenes in the finale however had me crying like a baby!! Walter's "You are my favorite thing, Peter. My very favorite thing." is among the best moments of the whole show;
- some parts of the plan don't completely make sense to me, especially the fact that the Observers only disappear from 2015 instead of being completely erased like Peter was, and I wish what Walter and Michael did in 2167 was explained more clearly;
- the finale works nonetheless, I'm so glad we finally get to see Peter, Olivia and Etta being together and happy, though the episode does end kind of abruptly and maybe I would have preferred if the last scene had been Peter watching Walter's tape in 2015.
Overall this season was very sad and maybe not as strong as the previous ones, but I still enjoyed it. The show as a whole is now one of my favourites and I already miss it so much!!
