There's a perfectly logical explanation for Daran's miserable romantic record. Unlucky in love, he recalls all the successful hookups he's arranged for friends, family, colleagues, total strangers. When he finds himself at his ex-fiance's house on the evening before her marriage to another man, he wonders why he feels so destined to be so lonely while orchestrating so much love for so many others.

He's about to find out.

The world premiere of "The Celestial Social Service," a romantic comedy by Pittsburgh playwright David W. Dietz III, is very fun, very light and with a little editing could be very produce-able. Dietz touches on all the requisite bases: wry dialogue, character conflicts, misdirection, switched identity, slamming doors, plot twists and happy ending. And while his story bogs down a little in the first act, it's nothing that another edit can't fix.

The story begins in the slightly dysfunctional home of an elderly couple, their divorced, middle-aged daughter and her twenty-something daughter, who's engaged to be married. Beginning as a typical family comedy about an impending nuptial disaster, it grows to a farce of modern mythological proportions when Daran suddenly appears at their door.

Ross Blumen is wisely cast to carry most of the weight in this feather-light comedy. As his central character gradually accepts the bizarre reality of the moment and realizes his true identity, Blumen adjusts accordingly and is always believable, fleshing out what could have easily been a cartoon role.

Megan May plays up the devilishly sexy cartoon qualities of her character, while South Park newcomer Emily Lorini's distraught bride-to-be keeps it real.

While a little over-exuberance in straw hat romantic comedies can be expected, director Christopher Scott gives the cast too much leeway, resulting in a performance by Marianne Shaffer that is overplayed to the point of distraction. Paul Laughlin, Toniaray DiGiacomo and Jerry Weinand are better in their roles.

Fans of light summer fare like to get the interrelationships out of the way and get right to the conflict. Dietz is a bit sluggish in setting that up, resulting in some slow moments in Act 1 that left the crowd shifting and distracted. With a little nip here and little tuck there, however, Dietz could have a fun little romp that could play anywhere.
