Its focus on Tony’s father’s former mistress lacks the intensity viewers expect from the series.IMDbThe Long Night – Game of ThronesThe massive battle against the White Walkers should have been a defining television event.

Even fans who love the show often rank it near the bottom.IMDbThe Last Christmas – Modern FamilyThis late-series holiday episode is frequently cited by fans as one of the show’s weaker efforts.
