SPOILER ALERT! don't read if you don't want details from the movie!
I am still not sure what Disney was aiming at when they made this movie. It certainly doesn't seem to have been made with kids in mind since it is quite scary in parts (e.g., when the ghost of Christmas Present dies, rots, turns into a skeleton and then blows away; or when you see nasty, creepy disgusting Ignorance and Need under his cloak -- my kids were like, "why did they have to have those 2 scary kids in the movie?"; or when Scrooge falls into his own open grave that is basically the fiery pit of hell). It was also very true to the original dialogue from the story which is basically impossible for kids to understand, so that when Scrooge's girlfriend is talking about how he's changed and she's releasing him from his "contract" (engagement), my 9 year old daughter looked at me and asked "what's going on?". And then the stuff that they added seems just bizarre -- like a miniaturized scrooge being chased through the city by a giant team of terrifying black "death horses" that goes on and on and on.
I think if I had seen it by myself, I might have thought it was a good movie, though not really any valuable addition to the Scrooge "genre" (if there is such a thing). But with kids, I cringed through a lot of it and wondered who in the world Disney thought they were making this 3D cartoon movie for.
