Middling Gallic dysfunctional-family seriocomedy “The Day I Saw Your Heart” is a slick but trite diversion toplining Melanie Laurent as a Parisienne whose hapless lovelife stems from poor parenting on the part of her boorish dad (Michel Blanc). Laurent’s reunion with writer-helmer Jennifer Devoldere (following Devoldere’s 2009 debut feature, “Jusqu’a toi”) opened last year in French-speaking Euro territories; despite Film Movement’s U.S. theatrical pickup, it seems more likely to find offshore success as a breezy cable and rental time-filler.
Justine (Laurent) is an X-ray technician staying with sister Dom (Florence Loiret-Caille) and brother-in-law Bertrand (Sebastien Castro) in the wake of her own latest breakup. She’s left a trail of brokenhearted beaus, blaming her serial relationship failure on the formative influence of childish, insensitive dad Eli (Blanc). That past also casts a shadow on childless Dom’s efforts to adopt, and on the newly announced pregnancy of Eli’s young second wife (Claude Perron); meanwhile, Justine finds a possible Mr. Right (Guillaume Gouix). Mildly amusing, the pacey pic piles on further complications without accruing much depth of character or feeling. Twee English-language pop tunes add a sugary note to the pro package.
