Suspension of disbelief is a necessity--albeit a pleasurable one--regarding many aspects of this romantic comedy, not the least of which being that either of its good-looking leads would ever lead lonely existences. Reese Witherspoon plays ambitious medical intern Elizabeth, who regularly clocks in 20 hour days at the hospital. Her work is her life, much to the chagrin of her sister Abby, who is married, with kids, and constantly attempting to get Elizabeth to go out more. When Abby finally succeeds in setting up a blind date for her sister, Elizabeth has an accident en route while driving to meet the mystery man, and the stage is set for love.
