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.
Crowning Moment of Heartwarming: When Santa makes it possible for the Lonely Rich Kid to be able to see him as he is and the little boy immediately hugs him on sight. Plus, pretty much any moment Lupita is on the screen.
A more straight example is Pitch getting the three boys to fight amongst each other. It's the only time he actually seems evil, with appropriate music (for a change) - a menacing slow bass piano riff..
Pitch: Go ahead, beat your brains out! At least I got them fighting — Lucifer will be so pleased.
Hell. Yes, there are demons dancing around in Hell, in a Christmas movie. What were they thinking?
Paranoia Fuel: Santa has a machine that can see your dreams.
Santa can also listen in on your private conversations. *shudder*
