The glassy-eyed, almost sinister prettiness of Zooey Deschanel colours the spacey, detached mood of this romantic tragicomedy. Despite clever moments and Hornbyesque touches of melancholy, it's let down by sitcom cliches, and by being weirdly incurious about the inner life of its female lead. Joseph Gordon-Levitt plays Tom, a failed architectural student who now has a stupid job composing gooey messages for greeting cards; the day he sets eyes on Summer Finn, his boss's gorgeous new assistant – played by Deschanel – is the day he falls in love.
