David Mirkin’s film Romy and Michele’s High School Reunion (B+) is a surprisingly winning female empowerment comedy with Lisa Kudrow and Mira Sorvino posing as impresario inventors to wow the folks they want to school with as they return to their ten-year get-together. Splashes of neon color, smart flashbacks, spicy writing and a potpourri of whimsical characters blend for an all-out comic joyride.
