KEN ZHU, one fourth of mega boyband F4, scores an F in acting in this winsome honey-dewy romantic drama, but co-star Gigi Leung nabs an A with her endearing pensiveness.

The thing about this is that they do not meet at all since he hails from the year 2002 while she resides in 1981 in a displaced-in-time kind of situation.

They communicate via a short wave radio, Dennis Quaid's Frequency style, exchanging thoughts about love and critical matters of the heart from their respective times.

As expected, he is a petulant cynic of our times with a girlfriend he ignores, while she, a romantic from an age less sceptical, has more enduring, lovey-dovey insights to offer.

Through a good plot twist, Leung's own tingling sensation for the love of her life, a fellow student, takes a sweet-sad turn. The guilty pleasure here is in knowing its bubblegum simplicity and picturesque emptiness and yet still falling for it.

Sky Of Love is no Il Mare, a smarter movie with a similar idea, but it does have the appealing Leung.

Shrugging off her lacklustre turn in Turn Left, Turn Right, she is sufficiently wistful here, competing as hard as Chu's long popstar locks for attention. She wins.
