Sitcoms are often called contrived, synthetic, formulaic. That goes double for Two of a Kind (premiering Sept. 25), which stars those twin charmers of Full House fame, Mary-Kate and Ashley Olsen
. The 12-year-old sisters play a pair of 11-year-olds who are identical but distinguishable: Mary-Kate's into sports and Ashley's into makeup. Their science-professor father (Christopher Sieber) is single, which makes him date bait, and a widower, which makes him ipso facto sympathetic. The new babysitter (Sally Wheeler) is hip and attractive, though Dad claims to find her annoying. Yeah, right. We've seen The Nanny. The redeeming feature here is Wheeler, who makes her free-spirited character genuinely appealing.
Bottom Line: Inoffensive but won't double your fun
