The table below presents all 144 episodes of Buffy the Vampire Slayer from the best episode to the weakest episode. The number in the "Points" column represents the average ranking that each episode received with 144 representing what would be a unanimous first place ranking and 1 representing what would be a unanimous last place ranking.
