They just created this sprawling world full of characters they haven’t managed properly and it’s abundantly clear that they didn’t have a long-term plan (or whichever one they did have was scrapped).

Most of the day-to-day of that has since been abandoned, and S3 pivoted into outright science fiction and had a fair bit in common with Stranger Things. it’s not that it’s bad, just confusing.
