Why It Rocks

 * 1) Mh:greatcharacters:Character development: Pacifica Northwest, the daughter of Preston and Priscilla Northwest, redeemed herself after she saw the truth about the Northwest family and because of Dipper Pines.
 * 2) Great animation as always.
 * 3) Funny subplot from Mabel and her friends.
 * 4) Preston got up his comeuppance when the gates are open all of the citizens of Gravity Falls were invited.
 * 5) The backstory of the Ghost of Northwest Manor is very dark, which means the creator, director and the writers were sending us the message and weren't afraid to talk about greed, betrayal, hard work and sacrifice.
