Donning fedoras and trench coats, the Olsen twins reprise the roles of pint-size detectives from their home-video series. Their motto: “Will Solve Any Crime by Dinner Time.” While their family is on a cruise ship, someone steals their dad’s laptop, which is encoded with some really, really important information. Their parents are played by real-life spouses Tracy Nelson and Billy Moses.
Solving the case involves gags galore, several chase scenes on the promenade deck and musical numbers shoe-horned in all over the place. It makes for a busy though emptily precious special. At least the girls get to wear cute outfits. With. Full House, the twins’ meal ticket, going off the air next month, I hope they cut a deal to keep the wardrobe.
