Sitcoms are simple. I know that sounds kind of odd coming from someone who has written a frankly embarrassing amount of articles analyzing the medium, but they really are. A group of people, either a family or friends/coworkers who function as a sort of family, gets themselves caught in a situation and hilarity ensues (Hence the name, situation comedy). Storytelling wise, a sitcom is as formulaic and simplistic as they come.
Over the years, people have tinkered with the formula. The most revolutionary innovation being the introduction of serialized stories, or plots that last longer than one episode. The basic sitcom formula necessitates that all conflicts and plots should be wrapped up in a neat little bow by the end of each episode. Early innovators like Cheers changed the game by telling stories that played out over entire seasons. Those stories weren’t that complex or hard to follow, most of the time they were just standard romantic comedy plots (Boy meets girl, boy likes girl, girl likes boy, they don’t get together for what seems like forever, you know how TV romance works).
But the saga of Sam and Diane paved the way for TV comedies to tell more complex stories than ever before. Though that might sound like a good thing, it has become a double edged sword. Some writers are compelled to tell stories that are too complex and lose the comedy (Remember The Comedians?), while others go all-in on one serialized story that doesn’t connect with viewers (Still lookin’ at you, The Comedians). The other side of the coin, however, is TV’s best comedy: HBO’s Silicon Valley
