Season 1 was a little boring, but pretty good. Season 2 was mostly filler. The show didn't really feel like stranger things after the first 2 seasons, but it evolved. Season 3 is 🔥. It's The funniest, most entertaining season. Season 4 is stranger things scariest, darkest, and best season. Season 4 is the peak of the series.

I also thought that the season 3 finale could've been the series finale if they removed the after credit scene.
