What do you think is the most formulaic TV show? My vote would go to Scooby Doo. Throughout most, if not all of the versions, almost every episode proceeds like this: the gang are riding in the Mystery Machine at night, with one of them giving some brief exposition like "It sure was great that your aunt [insert name] allowed us to visit their house" or whatever. They stop off in some town, are warned of a ghost, and a couple of red herrings for the culprit are introduced.
Fred says they should split up and look for clues (normally, between Fred, Daphne and Velma, and Shaggy and Scooby), Shaggy and Scooby mess around trying to find some food, the ghost runs after them, Shaggy and Scooby put on some costumes and do a little skit to confuse the ghost, and then everyone has to run and hide from the ghost in a music-filled montage. They meet back up, organize a trap that includes Shaggy and Scooby being used as bait after they're bribed with Scooby Snacks, the trap fucks up but the ghost is caught anyway and is revealed to be some guy trying to scare people for some plot of financial gain.
