That's just the first half of this year of The O.C., and we haven't even gotten to the adults yet. Both Sandy and Kirsten found themselves tempted away by more-than-willing suitors, and wicked Julie Melinda Clarke, Marissa's mom, cheated on new husband Caleb Alan Dale with ex-husband Jimmy Tate Donovan. An extremely tangled web was woven, one from which the show almost didn't recover: the Lindsay storyline started out strong but went nowhere, Sandy's ex-girlfriend Kim Delaney was a bit of a bore, and the same-sex relationship between Marissa and Alex never really gelled. All seemed like sure-fire character additions, but it was the later peripheral characters, including Billy Campbell as a magazine editor smitten with Kirsten and the menacing yet sexy Logan Marshall-Green as Ryan's ex-con brother, who injected The O.C. with energy, and helped steer the show back on course. Brody, who became the show's de facto poster boy, got to show off his comedic talents with the wonderful Bilson who rode the Zach-Seth-Summer romantic triangle most smoothly, and the heretofore sullen McKenzie got to lighten up quite a bit, until the show's violent yet effective season finale.

Forsaking a good amount of its comedy for drama, The O.C. got a little too seriously soapy, but its characters were so compelling you couldn't stop watching--even waiflike Marissa grew some edges. Clarke's scheming Julie was a constant pleasure to watch, and Rowan turned Kirsten's late-season downturn into a steely yet heartfelt portrayal. Despite the bumps, The O.C. remained one of the most exciting shows to look forward to week after week, a soap with smarts thanks to its fresh dialogue, gifted cast, and careening plot arcs. --Mark Englehart
