These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Bile Fascination: The primary interest most people have in it is how it shows everything wrong with Christmas movies.
Family-Unfriendly Aesop: Conformity and Commercialism are good. You know things are bad when even the movie itself points out how the tone would shift drastically if the Kranks were any other religion besides Catholic.
Informed Wrongness: In the end the audience is somehow supposed to agree with the neighbours that the Kranks are being selfish in wanting to celebrate the holidays on their own terms and not be bullied into conforming with everyone else over a tacky competition.
What an Idiot: Both the crook that the cop picks up near the end of the movie, and the cop himself. The latter because, instead of driving him down to the station after he drops off Blair and her fiancee, decides to leave the man unattended in his car while he goes to the Kranks' party. The former because, even though he manages to escape the car with the help of a gullible kid, decides that instead of just counting his blessings and making a run for it, he'll just break into the house the policeman's in and steal some things.
The Woobie: Nora, espicially during the ham scene.
