Love blossoms between improbable couples in this double bill of small-screen romances. Mary & Tim stars Candice Bergen as middle-aged widow Mary Horton, who faces public scorn after taking up with a mentally impaired handyman 30 years her junior. In Ronnie and Julie -- a modern retelling of "Romeo and Juliet," with politics and subterfuge adding an ominous kink -- feuding families keep their smitten teens (Joshua Jackson and Margot Finley) apart.
