10House of Yes (1997)
For a holiday that's a prime target for tales of dysfunctional families, House of Yes may just take the pumpkin pie. Marty Pascal (Josh Hamilton) is coming home for Thanksgiving with his fiancée Lesly (Tori Spelling) for the first time. Unaware of anything out of the ordinary, Lesly gets a crash
course in the Pascal family's strange behaviors.
Starring Parkey Posey as Marty's twin sister Jackie, a woman suffering from an obsession with both former first lady Jackie Onassis and her brother Marty, House of Yes isn't a movie you want to watch with the kids around. With themes of incest, murder, and mental illness, this is a great dark comedy, which is far less saccharine than the traditional holiday fare.
