I think my biggest complaint about the season as a whole, was that it took us all the way until the last episode to get the whole cast together. They way they had everybody grouped was good, but I still would have liked it better if we got more of everybody together.
I liked Erica playing a bigger role, I thought she was pretty funny. It's pretty much a tradition for these kind of stories for there to be at least one character who calls the others out on the crazy bullshit, and I thought she played that role pretty well.
I was disappointed they killed Alexi, I was kind of starting to like him.
I liked Robin a lot, she was pretty fun. The reveal that she was gay was unexpected, and I was pleasantly surprised by Steve's reaction.
I didn't really have a problem with Cary Elwes, yeah his character was a douchbag, but I did a good job, and he wasn't quite as over the top as the news paper guys.
I'm not sure who was scarier, the big gooey monster, or the Russian Terminator.
I have to agree with the people who said Mike was being kind of an asshole at times, but with the way they had Max and the other calling him out, I'm thinking that was kind of supposed to be the point.
I was kind of shocked they actually managed to make me feel bad, for Billy, but it was cool that he actually got to go out on a heroic note.
I did not expect Hop to actually die, that was a huge shock.
I'm curious if we'll find out what became of the big gooey Mind Flayer monster, because I'm thinking the fact that it's body is potentially still around might be important. I have admit, I half expected it to turn back into the people it was made out of when it died.
I wonder what the Wheelers and Eleven leaving Hawkins will mean for the future of the show, if it has one. Are they just going to end up getting dragged back by whatever happens next, or could we see the scope expand beyond Hawkins?
The mid-credits scene was definitely interesting. It's pretty obvious that Russians' American prisoner is Hopper, we never actually saw him die, so I'm pretty sure he's still alive. I could maybe see it being someone else, but there would have to be a pretty good reason for Hop not to go back to Joyce and the kids, I just can't see him staying away for 3 months without a very, very good reason.
