Watching this years after it was released is a fun experience, especially with the period-piece placement of so many '80s elements. The acting is pretty good, too, with one exception, and the writing is fun, with one exception: Finn Wolfhard and "Mike" basically are so laughable and unrealistic, it's beyond annoying. All the other child actors are great, and maybe it is because the writing for their roles is better? Either way, the characterization of "Mike" basically begs a viewer to turn this off, and the actor in the role is so bad. He was bad in the Ghostbusters movie, too, playing the same character basically, so ... maybe it's not the writing. Either way, fast-forward through all his scenes, and this will be a perfect-10 series.
