40 TV Shows That Never Got Better After Season One
Beginning a new show can and should be thrilling for viewers. However, first-season magic can be hard to replicate once it ends, and while many shows can, and do, find gems season after season, there are others that struggle to capture the brilliance of that first season.
To determine the TV shows that shone brightest in season one and then never again, 24/7 Tempo reviewed episode-level data on audience reception from IMDb. TV series were ranked based on the percentage difference between the average IMDb rating for episodes in the first season and the average across all other episodes. Only shows with at least 40,000 IMDb user reviews total were considered.
