Barb and Matthew sleep together. Which means Barb has slept with Christine and her brother. Which is just kind of weird. But then this is the same show that had Old Christine dating New Christine's father, which could have made Old Christine into her ex-husband's mother-in-law and into her own son's step-grandmother. But I guess that oddness is what makes "Christine" funnier than it should be.

If even half of Olivier Dahan's robust film about Edith Piaf's life is true, it's a wonder she could get dressed in the morning, let alone forge a legendary singing career. But the movie exuberantly argues that her emotional aches and pains sustained her, while the physical ones did her in. As Piaf, Marion Cotillard creates a spellbinding creature who is at once intensely physical and incontrovertibly sad. She won this year's Best Actress Oscar. In French, with subtitles.
