A previously excellent nostalgia exploitation show hit fourth season to rave reviews saying it's dark and serious and still excellent. It's not. First six and a half (of seven) episodes feature mostly teenage angst and high school drama played by men and women who are now all of them too old (some ridiculously so - Joseph Quinn) to seriously represent high schoolers, even failing ones. Ok, that's not such a big deal, although it messes with my immersion. The real problem is a whole lot of nothing on screen. Hopper is stuck in his own version of passion (Christ's kind) with a dull subplot that's slowly going nowhere. "Kids" are fighting "kids" in every way possible, from boring and insignificant drama to ridiculous, overblown vigilantism and mob justice. Fantasy elements are few and far between taking maybe 5 percent of each episode. Horror is rarely present and I cannot believe this is considered dark and sinister by many reviewers. But, probably the worst decision was to make what are essentially nine full feature films with the material for at most two.
