"Love Me, Loves Me Not," a nes CBS romantic comedy series, officially begins tonight at 8:30 on Channel 9. Some will love it, some will love it not.

Judging from the pilot that was broadcast Sunday, those who love it will be those who like stories of crazy kids in love. The young man, played by Ken Gilman, seemed crazy indeed as he courted the young woman, played by Susan Dey. She appeared more sane and resisted his efforts to attract her affections until the kookiness of it all proved irresistible.

Kookiness is presumably quite resistible to some viewers. They are the ones who will love this show not.

Regardless of whether the show is loved, however, it should be liked for the way it looked Sunday. It's a rare comedy series that does any exterior shooting these days - "M*A*S*H" seemed apparent in the performance the rule. Much of "Loves Me, Loves Me Not" Sunday was shot outside. We looked down on a huge lawn and up at a highrise, with actors on the balconies. One scene occurred on a real boat in a real bay. It was a refreshing change.

Susan Harris, who created the illfated "Fay," and her partners Paul Witt and Tony Thomas are in charge of "Loves Me, Loves Me Not." Jay Sandrich directed the pilot, and his experience as the principal director of "The Mary Tyler Moore Show," seemed apparent innthe performance of Dey. Formerly the oldest girl in 'The Patridge Family," Dey has a way of turning her head, of checking her speech, that is reminiscent of a young Moore. With the older Moore gone for a while, Dey might suffice as a temporary substitute.
