Uncle Frank

Uncle Frank is a supporting antagonist in the 1990 Christmas comedy film Home Alone and its 1992 sequel in Home Alone 2: Lost in New York. He is the uncle of Kevin McCallister.

Why He's A Total Scumbag

 * 1) He treats everyone he interacts with poorly, and the only characters we ever see him interact with are his own family.
 * 2) He is an absolute cheapskate, as in the first film, when the pizza guy hands him the pizzas and asks for money, Uncle Frank says that his brother can be the one to pay for the pizzas since it's his house. In the second film, he goes on vacation on his little brother's dime, and he continues to act like a complete idiot. Kevin is VERY right to call him out on being a cheapskate.
 * 3) He was at his absolute worst when he called Kevin, who just spilled some milk, a "little jerk". Who in the world talks to their own 8-year-old nephew like that?!
 * 4) He compares the situation of the family forgetting Kevin to the situation of him forgetting is reading glasses, which are far less important than the well-being of his own nephew, which he obviously does not care about in the slightest.
 * 5) He smashes his own child's face up against a wall with a chair and does not show any concern whatsoever.
 * 6) During the flight to Paris, he tries to steal some glassware.
 * 7) In the second film, he threatens to slap Kevin silly when he notices Kevin spying on him in the shower. Yes, Kevin should not be looking at him when he's showering, but that is not a good reason to slap him.
 * 8) He laughs at Kevin when Buzz humiliates him during the Christmas pageant.

The Only Good Quality

 * 1) He does at least cheer for Kevin when Buzz allows Kevin to be the first one to open up a present at the end of the second film.
