Ann Brashares' hit teen lit novels come to the big screen in all their girly glory. The story concerns four post-high school best friends who are drifting apart. Their assorted stories are all tied together by a pair of "lucky" jeans that are passed from one girl to another. Director Kan Kwapis (The Beautician and the Beast, Dunston Checks In and countless TV sitcoms) rounds up a herd of young hotties (Amber Tamblyn, Alexis Bledel, America Ferrera, Blake Lively), which should be sufficient to please the 12-to- 5-year-old crowd. 119 minutes PG.
