Darkness-Induced Audience Apathy: Davey is so unabashedly awful throughout the film that the only possible way to make him seem sympathetic is to make the townspeople even worse to Whitey.
Designated Hero: Davey, of course. He is an asshole to just about everybody and commits a lot of crimes such as vandalism, theft and assault. Yes, he does learn to be a better person later on in the movie, but still.
Ear Worm: Even people who don't like this movie (or Adam Sandler in general) have admitted that the songs are pretty catchy.
One of the biggest criticisms for this movie was how Davey does not deal with his loss the way most people really do, and rather than be introverted and antisocial is a troublemaker. Years later, Adam Sandler would star in Reign Over Me, one of his few dramatic roles where he was hugely praised for his sincere portrayal of someone who lost their whole family to a tragedy.
Jerkass Woobie: Davey, after you learn that his parents died when he was a boy. On Hanukkah, when they were on their way to watch his basketball game. Which, before he learned of their deaths, he worked himself to the core winning as a tribute to not only his parents, but to the parents who always came to watch their kids play basketball... despite the fact that they never win. Hoo-boy
Moe: Whitey. Even with his unbearable voice, he's still pretty lovable in his own way.
What Do You Mean, It's Not for Kids?: Yes, it's an animated wacky holiday musical rife with toilet humor, but it is most definitely not for children, what with the focus on deer shitting lots of poop. Doesn't help that in Canada, the movie's rated PG. 14A would have been more like it.
WTH, Casting Agency?: Adam Sandler as Whitey. He gives him a voice that's both irritating and unfitting for the character.
The Woobie: Whitey. Whether you like him or not, it is sad to feel like you don't exist by having someone you've been trying to make into a better person tell you so.
