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 Music of Awesome: The part where the Ghost of Christmas Present takes Scrooge on an aerial tour of Victorian London makes the already magnificent sounds of Hark! The Herald Angels Sing sung by a full professional choir even more epic.
Not to mention "God Bless Us Every One", performed by Andrea Bocelli.
Fridge Brilliance: Marley being stuck as a spirit gains a new explanation in this version. At the funeral scene, the first thing Scrooge does is steal the coins from Jacob Marley's eyes: The custom of putting coins on the eyes of the dead stemmed from a superstition that unless blinded, the dead could open their eyes and seek out others to join them in death, but an even older version of the custom dates back to Greek Mythology: When your soul entered the afterlife, you would be ferried across the River Styx by Charon, the ferryman, who required payment. Two coins were left with the bodies so that they could be used to pay Charon. Scrooge stole Marley's coins, thus Marley can't pay his way, so he is Barred from the Afterlife.
Tear Jerker: When seeing the Christmas Yet to Come, Ebenezer being the only one to see Bob Cratchit's raw, unfiltered, soul-wrenching despair after he hid it from his family. Just staring into that broken face from a man who was so jovial and happy is one of the biggest breaking moments for Ebenezer.
