I am astounded by most of the actors on this show. I can't think of another show where I have come to care for so much for a group of people in a relatively short time. While the writing is certainly a part of this, the performances really put it over the top.
I think that I might connect so well with the show as I would have been roughly the same age as the characters. Although the 80s depicted on the show is slightly different than the 80s I lived through, I definitely was hit with waves of nostalgia as I watched. I could certainly see myself being friends with the main characters--that is, if I had friends at that point in my life.
My only complaint is the level of horror and violence in some of the episodes. I know it would not have been as impactful without them, but I would have liked to share the show with my children. I suppose this just gives us an excuse to watch it again in a few years.
