As a parent of a 10 yr old, I thought the real, behind the scenes footage was great. Made my 10 yr old realize the hard work and sacrifice that's put in and she found it very inspiring.
For those that are familiar with this Dickens classic this is an ABSOLUTELY FANTASTIC remake. Not only was the movie itself well done, but the 3D was out of this world. If you are bringing small children with you, I suggest letting them see a different version of the movie so they are not caught off guard by the spirits.
