Pretty Little Liars provided seven seasons of mystery and dramatic twists, but there are harsh realities about watching it back five years after the show ended. Between 2010 and 2017, the Freeform drama series Pretty Little Liars ran on TV, garnering a large fandom. The series follows four friends – Aria, Spencer, Emily, and Hanna – who get blackmailed and tortured by a mysterious figure called "A." Throughout the series, other Pretty Little Liars characters like Alison and Mona join the Liars in their misadventures as well.
