“For a Good Time, Call ...” is a modern-day sex farce made for millennial and Generation X women. Even though the story is built around two girls starting a phone sex chat business, the movie is really about girlfriends taking care of each other when just about everyone else is letting them down. Lauren (Lauren Anne Miller) is a repressed good girl stuck in a cold relationship with her self-centered, live-in boyfriend Charlie (James Wolk).
