There's always a bunch of let's-see-what-this-looks-like viewers, viewers who don't really have the intention to watch the entire show. Another reason could be that they weren't interested in the next generation, but that doesn't say anything about the quality of the show. Or maybe they had expected more sex & gore & vampires....who knows? When I watched the first (and in my case, only) episode of "Stranger Things", it suddenly dawned on me that I never liked those 1980s King/Spielberg movies in the first place. So, obviously, this wasn't going to be my thing. But that doesn't make it a bad show.
