Lolo, the second French feature from writer, director and actor Julie Delpy, holds so much promise in its quippy, sexually risqué opening act. There, Violette (Delpy) and her best friend (Karin Viard) talk candidly about sex in their 40s, sex on their periods and other sex varietals that preoccupy these workaholic career women. But by the film's second half, Delpy has introduced a putzy love interest (Dany Boon) and a sociopathic son (Vincent Lacoste), both of whom somehow have the ability to get the otherwise ball-busting Violette to eat out of the palms of their hands. A cameo by Karl Lagerfeld is a welcome distraction part way through Lolo, but it is a mere flash in the pan of the movie's interminable 99 minutes. Clumsy and erratic, Lolo is a slapdash comedy of errors that slips on its own banana peel but gets few laughs. Tant pis!
