You may think you’re about to watch a fresh episode of one of your favorite series, but as the show is half-way through, you notice that you have practically seen a story before. Is this déjà vu? No, it’s just the laziness of the writers.
Every now a then, a show or group of shows tied to one writer/producer will repeat a plot that it has previously shown. Either the writers have effectively run out of ideas or they really need some time to recharge.
Note that this topic also includes copycats. In this case, one program totally rips one plot or premise from another.
