Contrast that with, say, Beverly Hills, 90210, which aged remarkably well for a 30+ year old series. It too gets rather self-serious at times, but the acting talent was really good and well-directed and they play their parts with a sort of relaxed, open California swagger that makes them seem honest and likable. 90210 has some interesting cinematic choices as well: the colors appear saturated but both the video and audio are soft and fuzzy, for what I guess is sort of a wistful look that seems less like how things actually happened and more like how the main cast's older selves remember it happening.
Some exceptions exist, of course. Stranger Things is incredibly well acted and goes for 80s verisimilitude, right down to authentic Tandy props and making the bedrooms look like they came out of E.T. with the lighting and set decoration. I Am Not Okay With This has a real honest feeling to it as well. They shot on location in Brownsville, PA, and really tried to capture the feel of the town in the background.
