I didn't like all of the main characters except for Ted Baxter being fired from the WJM newsroom on "The Mary Tyler Moore Show," but I still treasure that show for its first class writing and acting.
"Seinfeld" ended on too much of a sour note for my taste, but the episodes I enjoyed most, such as "The Chinese Restaurant," "The Jacket," and "The Phone Message," are still as humorous to me as they were originally.
I also wasn't crazy about the way "How I Met Your Mother" ended, but that hasn't stopped me from appreciating the friendships between the core characters and revisiting the show via podcasts.
There's more to a sitcom than its last episode.
