Frothy, funny and formulaic, 27 Dresses is a pleasantly predictable romantic comedy that sees Katherine Heigl following “Knocked Up” with smooth moves at the wheel of her first starring vehicle.

It delivers everything you expect on a timetable you can predict to the minute. It's filmmaking as a cross between a carefully choreographed dance and an elaborate pageant.

There's not a surprising moment in the movie yet it works in spite of the stale, insipid storyline. That has a lot to do with lead actress Katherine Heigl and a little to do with the glowing embers between her and her co-star, James Marsden.

27 Dresses is a movie geared to a pitch of high matrimonial-princess fever.

While Heigl is terrific, this uninspired romantic comedy is considerably less so.
