Unconvincing musical drama, a remake of 1938's "Four Daughters", has bright, cheery Doris Day picking brooding Frank Sinatra for a suitor over bright and cheery Gig Young. She's hoping to cure Sinatra of his demons, of course, and isn't true love the best medicine after all? A corny, artificial outing, although one mounted with classy studio-style and featuring pleasant supporting characters and chipper family chit-chat. Still, Sinatra's dour mood and Young's attraction to Day (over one of her sisters, whose tender emotions are never quite dealt with) leaves one unsatisfied. It's certainly a well-scrubbed, family-oriented diversion, but the all melodrama the screenplay brings up seems wrong-headed, and sour Sinatra never fits in with this sunny family and he never clicks with Day. **1/2 from ****
