For all its limitations, the film still looks terrific. Flawless CGI and forays into animation keep things visually lively, and Nim’s enviable life is likely to hook kids into the story early and keep them entranced.

Some nice scenery, an unexpectedly funny performance by Jodie Foster and a unflaggingly spunky Abigail Breslin make for above average family entertainment.

Even as the derivative roots of Nim's Island are clearly visible, kids will no doubt vicariously enjoy Nim's adventures and Edenic existence. And how refreshing, for once, to see a girl embark on derring-do that, in Nim's own words, makes her the hero of her own story.

This family comedy adventure from Walden Media is likable in a scruffy way. Its characters, especially the youngest one, are engaging, and few adults are immune to childhood fantasies about secluded tropical isles.

If you're an elementary schooler or someone who finds Gerard Butler irresistible even when fully clothed, Nim's Island may be a treat to watch. If not, it's likelier to be a chore.
