The idea of Nim living on her own private island with all kinds of interesting animals and fighting off bad guys on her own was appealing to my kids. However, my 7 year-old was concerned that Nim's father wouldn't return, and my husband couldn't understand how he could leave Nim alone on the island, especially after her mother had apparently been lost at sea! The animated sequence about Nim's mother being swallowed by a whale was a bit disturbing,too. I love Jodi Foster and, although my kids didn't understand all the references to her character's mental issues, they did get that she was "crazy" and had to overcome her fears to help Nim. The movie's happy ending seemed to make up for the anxious moments, its (almost) total lack of bad language was refreshing, and overall we enjoyed it a great deal.
