That Debra Messing’s precise comic timing and dazzling demeanor – two qualities of Golden Age comediennes – still manage to shine in this clumsy romantic comedy only distinguishes her underused talent. Here she’s a single woman who hires an escort (Dermot Mulroney) to pose as her boyfriend at her sister’s wedding. The leads have plenty of chemistry, yet one of the many structural problems is that it’s there long before their characters have earned it.
