The part where they morse code to find out Will is still in there felt totally repetitive of season 1 with the alphabet on the wall. You can call it a callback, I call it unoriginal.
Eleven and a dude with a shotgun takes out the big bad in five minutes. Kind of ruined the ending. Also big scary CGI tentacle thing reaching out through the portal didn't look great, especially when we got fairly decent CGI monsters throughout the season (for a tv show).
I didn't like that the story with Eight didn't go anywhere except teaching Eleven to hate and love.
It was a nice departure from trope that the evil looming corporate business conglomerate D.O.E extension was actually trying to do right, and wasn't running around offing people.
Even with that taken into account, it was a 9/10 season for sure.
For next season, we got a demadog in a freezer, Eight running around causing mayhem, a loose spirit that came out of Will, Max's brother still getting beat up at home (I mean, you got to have some sympathy there), and the US invading the upsidedown looking for oil probably. It's going to be a long wait!
