What in holy hell is a "Mimzy"? Don't ruin it for your kids, but it's an artificially intelligent stuffed rabbit, sent back in time—with some funny rocks and a gelatinous blob—by a desperate future scientist. Yeah, it's a little far-fetched, but your offspring are almost certain to love it.
While vacationing on Washington's Whidbey Island, the Wilder kids, Noah (Chris O'Neil) and Emma (Rhiannon Leigh Wryn) discover a mysterious box containing the aforementioned items. The kids develop magical powers of sorts, but when Noah accidentally knocks out Seattle's entire power grid, an FBI anti-terrorist expert, played by Michael Clarke Duncan (The Green Mile) comes looking for answers. Rainn Wilson (NBC's The Office) plays Noah's goofy science teacher who notices something amiss and tries to interpret the tots' strange new powers. The Wilder parents, Jo, played by Joely Richardson (Nip/Tuck) and David, played by Timothy Hutton (The Good Shepherd) are largely unreceptive.
The content is geared toward a younger crowd and some of the prevalent sound effects from the mysterious goings-on were almost enough to make me want to box my own ears, but otherwise, this is the type of family film that kids will more than likely want to own and offers enough interesting plot twists to avoid sending parents into a stupor.
In short ... The premise is flimsy. But it's chock full of whimsy. So don't feel bad about renting Mimzy. (I feel just awful for having written that.)
