Some television shows start off with a bang, featuring incredible first seasons that feel tightly written, and impossible to stop watching. But sometimes the mystery goes too far, the characters become exaggerated versions of themselves, or the writers simply run out of ideas after an explosive start. In other cases, network pressure and popularity push a concept well beyond the point where it naturally should have ended. What makes these shows especially frustrating is that the first season often remains genuinely fantastic, reminding audiences how strong the series once was before things started falling apart. These are the shows where the debut season still gets recommended, even when longtime fans quietly warn people to stop there.
