Identical twin 9-year-old girls, one a poor orphan, the other a rich heiress, cause confusion when they decide to meddle in their caretakers' love lives in this family-oriented comedy. Amanda (Mary Kate Olsen) is the orphan, a scrappy young girl with no family, relying on the support of her caring social worker, Diane (Kirstie Alley). When Diane brings Amanda to a summer camp, she first encounters Alyssa (Ashley Olsen), the wealthy daughter of the camp's sponsor, Roger Callaway (Steve Guttenberg). The girls immediately bond and decide to switch places for the fun of it. They soon conclude that their lives would be improved if Roger and Diane were to get together and form a family, and they set out to bring the adults together. More jaded, older viewers may be put off by the film's saccharine tone and derivative, Parent Trap-like narrative, but the inoffensive humor and the presence of popular TV stars the Olsen Twins should appeal to family audiences. ~ Judd Blaise, Rovi
