Uneven and sloppily sentimental, "Life as We Know It" is still the best Katherine Heigl comedy since "Knocked Up."

Credit her co-star, Josh Duhamel for that. As he has done in many a less-worthy romantic comedy, he amplifies her charm. And she, in turn, brings out his sweet side. And credit the script, which gives her more to play than your average "Ugly Truth."

"Life As We Know It" is about two seriously mismatched people - once hurled together on a disastrous blind date - suddenly bonded together for life when their mutual friends die and will them into raising their infant daughter.

Messer (Duhamel) is a womanizing, motorcycle riding TV director for the NBA's Atlanta Hawks. Holly (Heigl) likes her high heels HIGH, her life organized and she runs a hip bakery.

Director Greg Berlanti turns this film on a dime a couple of times - giving us decent tear-jerking moments, beginning with the one where the two not-friends mourn the loss of this young couple with a baby.

Life as they know it has changed. The they-can't-get-along comedy resumes, now with diaper jokes, projectile vomiting, drop-the-baby gags, and that magical babysitter who knows how to calm children.
