The Buffy the Vampire Slayer TV spin-off series, Angel, has an 88% positive audience rating on Rotten Tomatoes, but it has several plot holes that still bother audiences. Haunted by his violent past, Angel, the vampire with a soul, relocates to Los Angeles where he sets up a supernatural detective agency. Various Buffy characters appear in Angel, and he often finds that his past catches up with him in this way, despite his attempts to make amends. Angel has a darker tone than Buffy the Vampire Slayer, and one of the darkest storylines involves Angel's son, Connor.
