Compromise. That's what 'Life As We Know It' is ostensibly about, but from its far-fetched premise on down, it's a potentially touching drama compromised by rom-com routine and defined by the type of sparks that rocks give off when clashed together often enough.
Holly (Katherine Heigl) and Messer (Josh Duhamel), respective best friends of Alison (Christina Hendricks) and Peter (Hayes MacArthur) and complete opposites otherwise, find themselves bound together by the burden of caring for that couple's young daughter, Sophie (the equally adorable Clagett triplets), when they die in a car crash. Forget that Holly owns and runs her own business. Never mind Messer's perpetual bachelor lifestyle. The couple's final wishes -- in addition to an overwhelming sense of guilt and a conveniently covered mortgage -- dictate that these two must live under the same roof and juggle the plans they had with the duties they now face in raising a kid.
