TO HAVE & TO HOLD 9 p.m. Wednesday, WOIO-TV (19) "Tuned In" By STAN URANKAR October 15, 1998 Do we need need another cute, young, newly married couple on network TV? And do we need them for an hour? Under the dubious heading of dramatic comedy, "To Have & to Hold" pairs Jason Beghe and Moira Kelly as ambitious lovebirds with strong Irish roots. The comedy comes from learning to live with each other, as well as their good-stock families, who aren't far away in their Boston neighborhood. The drama comes from their occupational contrast: he's a police detective, she's a public defender. At odds by day, in love by night. The concept is awfully thin to sustain an hour each week. The pilot floundered between syrupy globs of mushy stuff and overdone helpings of career conflict, with Kelly's witness-stand questioning of Beghe an exercise in absurdity. Beghe doesn't sell as maybe the nicest plainclothes cop ever to hunt down lowlifes. He's always smiling, probably at his good fortune in landing a primetime series. If there's a redeeming quality, it's the unheralded Kelly, who has enjoyed a steady film career since her breakout role as an Olympic skating hopeful in "The Cutting Edge." Kelly brings a heartfelt warmth to every scene, bursting with quietly sexy radiance. Too bad even her captivating presence doesn't make "To Have & to Hold" worth holding onto. WATCH IT? Once, to have ... TAPE IT? ... but not to hold.
