- Critical Research Failure: The family becomes immortal after Nick is made a saint, despite the fact that one of the key requirements for becoming a saint in the first place is being dead.
- Funny Moments: THAT'S NOT ALEC!
- Harsher in Hindsight: Kevin Spacey is on the naughty list? You don't say!
- Heartwarming Moments: There's no naughty kids, Nick. They're all good kids. But some of them are scared. And some of them don't feel listened to. Some of them had some pretty tough breaks too. But every kid deserves a present on Christmas.
- Which plays a part in Nick's later action in the scene where Clyde gets the gift he always wanted from Santa.
- Also the entire Christmas morning sequence, with a beautiful rendition of Silent Night playing and Nick telling Fred he's the best big brother anyone could ever ask for.
- Tear Jerker: Nick's gift to Fred is a birdhouse with the note, 'I'm sorry I cut down your tree'.
- Unintentionally Unsympathetic: The message ends up being that theres no such thing as a truly bad kid. Even that budding sociopath who beat up his sister, apparently.
- The Woobie: Fred, YMMV on if he's bordering on Jerkass Woobie. Kinda hard to dislike him when you realise that for most of his life he's had to deal with his parents constantly telling him to be more like his brother, even though he was already kindhearted - he gets told off for getting upset that his brother just gave away the present he'd clearly put a lot of work and thought into, and without so much as a thought towards the effort he put into it.
- Nick as well, who is burdened and stressed by everything throughout the entire movie, and he's just so broken by it all near the end before the happy ending transpires.
YMMV / Fred Claus
