Well said. I loved this season and that's due in large part to this cast. They are an endearing group of young actors and I'm eager to see how they bring their characters to closure in the next season or two. I have no doubt that the Duffers will be able to finish this dark but delightful story.
I believe that David Harbour will be back. This story could go forward without him but it would lose its heart. And yes, it some ways it would be perceived as a cheat to bring him back but that wouldn't matter to me. I love these characters and their genuine concern for one another. I need him to return for El, Joyce, etc.
I was thrilled to see that Suzie was real, adorable and that she shared Dustin's feelings. Their song was great and as was the others' reactions. Some may complain that it went on for too long. Maybe...but I don't care. I loved it and, IMO, it added to the charm of this show.
Saddened by the move of the Byers + El. I'm sure that they will reunite next season, at least, temporarily to fight some new form of evil. Regardless, we know that all of these kids will soon be going their separate ways as they grow up.
