Kin (1998)

Our story begins when Greg convinces his girlfriend Nicole to take him to her family reunion in New Jersey. Bad move, Greg! The couple find their relationship on thin ice when they are forced to endure all sorts of oddball antics with the family, including cat discipline, Monopoly control freaks, a softball game from hell, and a Vietnam experience that is a comedy classic. This is a movie for anyone who has ever had to meet the folks and survived.
