We have loved this movie since my oldest (now 9) was 18 months old and wanted to watch it 24 hours a day. The scenery was beautiful and captivating for all ages even then; in 3D, it was just that much more so incredible to watch. All of us, ranging in age from 18 months to 37 years, kept our glasses on, ooh-ed and ahh-ed over the ocean, and just had a great time.
The 3D effects were not "in your face" as the movie was not designed to be presented in 3D; however, the impact of that third dimension on one's viewing experience was just as impressive as it in those movies designed to be seen through those special lenses.
