After really liking season one, I was disappointed by season 2. Although I still had a good time with it.
The writing felt rushed throughout, with too many new characters filling up time without justification. Characters often do things to satisfy the story ark, but in ways that are not plausible. For example why do the kids even decide to go under ground in the final episode when they torch the creature? Are they insane? It did not seem necessary, but is just thrown in there so that every character has something to do during the climax.
I hated the way the season left some key characters hanging without purpose. For example, Mike is given nothing to do. All he does is observe, and this is after being perhaps the heart of the first story. I am baffled by the show's inability to make better use of him. Furthermore most of the female characters are poorly written - Winona Ryder's mother has almost the exact same role as in season one, freaking out and making sense of patterns (this time drawings and the morse code thing - groan). The red-headed girl - Max - served absolutely no purpose. Why was she even written into the show? She contributes nothing. I was waiting for a big reveal of some kind, to learn she is related to Eleven or something. Nope. She just hangs around, sort of like Mike.
I was annoyed by the fact the writers broke up the kids, which was a tight Stand-by-Me-meets-It unit in season 1. Here they are spread out doing different things, which changes the show in a bad way - the charm of their friendship was key to the appeal of the first season. What sucked me into the first season was the character development, the investment in relationships and worldbuilding that felt real and engaging. Horror and sci-fi elements added suspense, but were secondary to all of that stuff. This season got things backwards, dropping the ball on character development and overloading us on thrills without establishing emotional investment. Watching this action I was beginning to forget why I was supposed to care in the first place.
Side characters were also poorly written. Sean Astin's rotund boyfriend has no discernible personality except to drive a plot point - he is good with puzzles - and then to die somewhat gruesomely in annoying slo-mo - just freaking run, fatso. And why couldn't they do more with Paul Reiser? I kept expecting some kind of nod to his backstabbing character in Aliens, in which he screws over the crew. But there is no surprise here either. (also can someone explain to me why the demo-dogs injure him but not kill him???)
More complaints. Are we really supposed to buy into the Nancy-Jonathan relationship? I don't think they have any chemistry. I much preferred her scenes with Steve from the first season. But maybe this is just me.
Oh and let me be among those who hated season 2, episode 7 - Eleven joining the gang of never-do-well superhero punks. It was like something out of network TV. Please fire everyone responsible for that thing and erase it forever from our memory. Dreadful.
Loved Billy Hargrove. May have been the only aspect of this season to really resonate with me. Completely captured the essence of the 80s movie villain.
