Jennifer Aniston gives a great performance in the black comedy The Good Girl. But that's no surprise, considering that the Emmy nominee's Friends job has basically been one big, eight-year-long rehearsal for her to play Justine, the movie's woebegone heroine. In fact, if only Justine had a better hairdresser and Rachel a Texas twang, they'd have loads more in common than even twin sisters Phoebe and Ursula. — Charlie Mason
