Living with Fran (2005)

Frantic Jewish divorcée Fran Reeves falls madly in love with Riley Douglas Martin, a hunky contractor half her age, who moves in with her and her nasty ex Ted's two adolescent children, timid med-school dropout Joshua 'Josh' and bitchy high-school girl Allison. They all have a hard-enough time finding out where they fit in this reconstituted, unofficial household, not an actual family, and things are even worse when outsiders wonder or ignore how it all works, given the shifted generations, Riley being barely older then his 'step-kids', actually an ideal big brother if only he were a sibling rather than the provider. Alliances and antagonisms shift, but ultimately true love triumphs and things work out.
