All I could remember about the film I was about to preview was that it was about a boat. As we switched our cell phones to silent another reviewer reminded me that it was based on a true story. I was surprised, therefore, to see the Disney logo come up on screen as I adjusted the 3D glasses I had, for once, remembered to bring. My expectations were primed: a story that would doubtless have a happy ending and one with great cinematic effects. I was right. And the journey there was a fine one indeed.
