Yep, it's worth noting that, while this is a Disney film, it's a pretty faithful adaptation of Dickens's book and not directly aimed at kiRAB. Most Christmas Carol versions aren't really aimed at children. The book itself is pretty spooky to read in places, and this version gets that across very well. Younger kiRAB WILL be freaked out by parts of it and probably not understand the story much anyway.
Jim Carrey pulled a real blinder as Scrooge. It's a really subtle performance for 99% of the time. Something difficult to do considering Scrooge is an animated character here. His voice as Scrooge is great, though his accents as the spirits are pretty dodgy but funny (somehow this made it more enjoyable for me). Gary Oldman is amazing as Marley (why wouldn't he be? it's Gary Oldman!!). Just think how many times the Marley scene has been done, well this might indeed be the best ever. It's certainly the freakiest I remember seeing. Again there's some humour thrown in but I reckon most people will be too shocked and engrossed to laugh!
Something I was impressed with was how well the last 10 minutes were done. We all know the story, Scrooge wakes up and the spirits have done it all in one night, he tells the boy to go and get the biggest turkey in the shop etc. etc. but this time it didn't seem to be done in just the usual slapdash way. Probably my favourite moment in the whole film was when Scrooge walked into Fred's house.
