The screenplay has pages I imagine remain only half-filled. Not long after Heigl and Kutcher meet in an elevator, they share this exchange. She: "Huh-huh." He: "Huh." She: "Huuuuuh." This is the language of love for two people coming out of a coma.
Is it some monstrosity of awfulness, as its lack of advance screening suggested? No, that would imply at least a spark of some kind. This is just an empty summer hodgepodge of stale romantic comedy exchanges, witlessness and lackluster action.
Everything has a thrown-together feel, as the characters are tossed from romcom situations to action set-pieces and back again with no thought to applying any sort of grace notes to ease the transition.
