"Pretty Little Liars" follows four estranged best friends who are reunited a year after the leader of their clique goes missing, only to realize that they're all receiving anonymous messages from someone who knows all their secrets.
Shows that I got bored with or that got significantly worse over time. Some of them have specific moments that made me stop watching (I'm looking at you, Dexter). A split-off of my "TV Duds" list, since I felt a lot of these didn't deserve to be on there, since they were good at one point.
Every show has an impact on the person watching it, some more than others. Make fun, ask questions, say what you will. These shows changed me for the better.
