By the time the hit Britcom Coupling reached its fourth season in 2004, change was afoot. Newly moved from BBC2 to BBC3, the show also faced its first significant casting change: Richard Coyle abruptly left the series, effectively removing spastic man-child Jeff from the tight, six-member ensemble that had been together for 22 episodes. Though disappointed, series creator Steven Moffat whipped up a replacement in the form of Oliver (Richard Mylan), a comic-shop employee with adolescent hang-ups and dating woes similar to Jeffs. Initially introduced as a peripheral character, Oliver soon blossomed into a love interest for kooky Jane (Gina Bellman). Meanwhile, Patrick (Ben Miles) and Sally (Kate Isitt) settled into their tentative romance, while Steve (Jack Davenport) and Susan (Sarah Alexander) dealt with their impending parenthood. Even as the show maintained the more mature tone of the previous season, some longtime viewers complained bitterly about Jeffs absence -- and about the obvious similarities between him and Oliver. Jeff did, however, make a memorable appearance in the season finale, though not in the form his ardent fans might have expected. ~ Brian J. Dillard, All Movie Guide
