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.
YMMV: Jingle All the Way
Crowning Moment Of Awesome: Liz hitting Ted over the head with a thermos of eggnog could be considered this for the whole film, knowing what a seductive and manipulative sleazeball he constantly is towards women; not to mention how he always is taking advantage of Howard's weaknesses and trying to make him look bad.
Family-Unfriendly Aesop: Buying your kids toys they want, even if you have to go through hell, is the best way to show you love them.
Not all that family unfriendly, actually. Going through great pains for one's children is something any parent can identify with, and Jamie wound up giving the toy to someone else. The film was actually very anti-materialism in the end.
Unless you consider the fact that, after the end credits, Howard's wife was expecting him to get her something as well. Subtly hypocritical, much?
No way does the film criticize or provide meaningful commentary on how Howard and Myron are only going through hell to get the toy to make up for not being there for their kids the rest of the year.
How about Johnny's dialogue to Jaime that Ted was a deadbeat dad too until the divorce, and suggesting that if Jaime's parents get divorced it could make Howard a better father. It doesn't help that the film seems to want to agree with Johnny.
Jerkass Woobie: Myron. Despite his flaws, the audience can't help but feel kinda sorry for him as it is implied that he lives a relatively crappy life—he works long hours to no reward or recognition, has no family, his wife cheated on him repeatedly and took custody of his son during their divorce, money is tight as a significant chunk of his income is sent to the aforementioned cheating wife for child support, and he seems to be generally treated unfairly by everybody in his life. So despite being an antagonistic character in the film, the viewer can't help but understand and emphasize with his cynical attitude and animosity for the holidays, even though he can be a bit annoying for the way he jabbers too much about rhetoric.
The Motorcycle Cop also is on a count of always falling victim to Howard and Myron.
Memetic Mutation: "Put dat cookie daughn! NAUGHH!" Thank Swede Mason for the mix.
Less memetically, "It's turbo time!"
Narm: Most of the son's lines, due to Jake's wooden acting.
Also, Howard's wife gets a very narmy scene. The line itself is simply "damn you, Howard," but it really cannot be stated how terrible the delivery is.
Strawman Has a Point: Admit it, some of Myron's views on the Christmas season and some of the points he makes on how the marketing divisions of toy companies stir up these major "crazes" for a new toy during the Christmas season for their own profit are rather valid.
Subverted by how he attributes him living a miserable life while his childhood neighbor went on to become a millionaire CEO is due to him getting the fad toy for Christmas during his childhood while Myron didn't.
