While it presents some fantastic ideas and includes enough larger-than-life elements to entertain any kid on a rainy afternoon, The Last Mimzy ultimately leaves your mind feeling like your stomach does twenty minutes after scarfing down a giant helping of Chinese food -- empty, confused and a tad bit guilty. Based on Lewis Padgett's short story, Mimsy were the Borogoves, The Last Mimzy marks Bob Shaye's (New Line's founder, co-CEO and co-chairman) triumphant return to the director's chair after 17 long years. But, unlike the campy Book of Love, Mimzy provided Shaye with more complex material and universal themes that, if pulled off properly, would leave the audience hanging onto the edge of their seats, rooting for two ordinary kids faced with an extraordinary task: to save the world. Sadly, the only thing I was hanging onto was a small piece of the armrest I shared with the little kid who fell asleep next to me.

Noah (Chris O'Neil) and Emma (Rhiannon Leigh Wryn) aren't superheroes or crime-fighting vigilantes; they're your average brother and sister out looking for a little fun as the family -- complete with mom and dad (as played by Joely Richardson and Timothy Hutton) -- arrives at their isolated summer home with a generous portion of rest and relaxation on the agenda. When a clunky black box washes up on shore, the two are immediately intrigued by the mysterious symbols etched into its side. What is this? Where did it come from? And why are there black rocks, a sea shell and a stuffed bunny rabbit inside? It doesn't take long for the kids to figure out that the contents of this box, while unusual, provide those in its possession with strange physical and mental powers. So, naturally, they do what any young kid would do upon discovering a priceless artifact -- hide it from mom and dad.
