Fanciful idea of Venus sending young son Cupid down to Earth via a pair of statues on Richmond’s Olympus Building zings with possibilities. But “Love-Struck’s” Lindsay Harrison-Stephen Witkin script needs tightening, and the production requires a lighter hand than Larry Peerce’s at the helm. Brighter secondary characters would help, too. It may be Roman mythology, but the Greeks have a word for it. Venus (Suzanne Somers), noting that attractive human Emily Vale (Cynthia Gibb) no longer believes in love since her breakup with dour Ted (Mark Joy), decides to send down 12-year-old Cupid (a confident Tyler Noyes) in the form of an adult (Costas Mandylor) who can tango like a whiz. He’ll put love back in her heart. Her girlfriend Rachel (Anabelle Gurwitch as a character waiting to be explored) falls for him, but Cupid’s arrow , aimed at Emily, ricochets back to him instead, and instantly he’s in love with Emily. Director Peerce doesn’t touch the farce possibilities. What would otherwise be a pretty thin premise trudges along as Cupid pursues Emily and Ted reappears. Cupid has the choice of returning to his mother’s side or turning into a mortal. He talks the madness over with good scout Emily, who’s in a quandary: Seems she’s taken to sexy Cupid, even if his is an odd name. Gibb turns in a sincere, sometimes delightful perf as the confused heroine. Ex-“Picket Fences” cop Mandylor looks the role, and with stronger acting guidance could have made a confident character out of the myth. Somers’ Venus, staying aloft, watches goings-on with a careful eye; not much for her to do. Idea’s too good to be dismissed, familiar or not. More rewrites would have been in order, reworking the dialogue and the supporting characters, who could have sparked the romantic comedy. As a legit musical, it might fare well. As it is now, “Love-Struck,” which could please undiscriminating viewers, fails to hit its target. Tom Priestley’s camerawork and C. Robert Holloway’s production design suffice. Other tech credits are OK, though there’s at least one slack editing seg.
