"Karin Viard's performance as the titular - and very happily and comfortably sex-positive - Pattie in 21 Nights with Pattie is a sheer delight. The film's central conceit of letting go in order to find one's self is memorably embodied by Pattie, a funny and sexy role that Miss Viard makes her own in a way that perfectly captures the film's consistent balance of effervescent comedy and spiritual profundity."
