As seen in: The recent The Walking Dead finale, Lost, shows that like cheap cliff-hangers, and The Sopranos' series finale (for some reason?).
If you know some The Walking Dead fans, you might be wondering why they were out in the street overturning burning cars after the recent season finale. Well, about six months ago, the show started teasing a major event that's already happened in the comics: the death of a main character at the hands of a new villain. The cast did publicity appearances talking about how they were already in mourning and how said event would arrive in the season finale and would shock fans to the core. AMC teased the episode with glimpses of the death scene with the tagline "THE PRICE WILL BE PAID."
