TV's Best Series Finales of All Time, Ranked: Cheers, Six Feet Under, Friends, ER, 12 Monkeys, S.H.I.E.L.D. and More

Just as all TV series aren’t created equal, neither are all series finales. Many are fine, a few are quite poor, but some are no less than fantastic.

On the heels of revisiting our rundown of TV’s Worst Series Finales Ever, we dug in our heels and took a long, hard look at our ranking of the greatest ones — of all time. As in ever. In history.

Starting off with our original Top 15 list, we reconsidered/added in a few series-enders from years gone by as well as included three from just the past 36 months. The result is a robust, exciting revisiting of the 25 Best Series Finales of All Time, including the utterly sublime swan songs of gritty dramas, big-hearted comedies and several genre-TV favorites.
