Season Four Peter Hale
I don’t know how the show could screw a character up as badly as they did, but Peter Hale is proof of too much of a good thing. He started out threatening and fun to watch and was turned into the worst character on the show, period. He takes away screen time that would be better spent with other characters, and his want for power and needling in other characters’ lives became contrived. I truly believe his continued presence aided in making season four the weakest in Teen Wolf’s run so far.
