"Televisions have been fixtures in American homes for decades, so choosing the 100 best shows of all time is no easy feat. Stacker compiled the data for all TV reviews available on Metacritic, averaging reviews for each season and ranking shows according to the highest average. To find a television show's cumulative Metascore, Stacker averaged the reviews for each season and ranked shows according to the highest averages. Live-action series, animated series, docuseries, miniseries, and series with only one season were included. The 'Series Metascore' represents the Metascore for all seasons that had data available, with the most recent available date from Aug. 31, 2020. Runaway successes like 'Game of Thrones' are absent. Beloved classics like 'M*A*S*H,' 'Seinfeld,' 'I Love Lucy,' 'Friday Night Lights,' 'Cheers,' and 'Law and Order'—with all its spin-offs—are examples of popular shows that, according to critics at least, aren't in the top 100." - stacker.com
