We took our entire family with children ages 15, 12, 10, and 7. The older three liked the movie and LOVED the visual effects, while the 7 year old was consistently scared throughout. The title says Disney, but it is not a movie for the younger ones.
That being said, I personally loved the movie. The visuals are stunning, and the story is true to the Dickens original (including dialogue). It must be seen in the theater to be truly appreciated.
