It is interesting how polarizing this show is on gaf. We actually went to the theater to see the final episode, it turned out to be a really cool way to spend the early part of New Year's Eve. Theater was completely packed, which was fun, and I'm old enough that I spent half the night glowing about the incredible parking spot I squeezed into just before walking in.
ST was fun, like many I really enjoyed the first season, somehow I was completely disinterested and just skipped S2. Tuned back in for S3 because I was bored & was pleasantly surprised, low expectations for S4 but got pulled in right away between the Nightmare on Elm Street meets Akira vibes (seriously, they handled all that stuff so well!) Although the second half of S2 felt excessive/cheap.
Final season was not half as good as S4, which I guess would be a tall order, but they did a satisfying enough wrap-up. I would have been much happier if they shaved off the last, oh, 45 minutes, but I guess they know what modern audiences want and this must reflect that.
I think the show would have benefited from a few less characters (tighten things up/less dilution) and the way they actually handled the ending of Vecna felt a bit over the top like a video gamer from 20 years ago designed it, but whatever, it was an ending!
