Fox was typically overzealous in its promotion of the “OC”‘s second season. Besides running two nearly identical, hour-long promotional cockteases (singular revelation: The Cohen pool is fake) and shelling MLB postseason play with breathless spots about the upcoming premiere, game four of the ALCS saw Summer spelling Bill Mueller at the hot corner. The frenzied buzz puts pressure on the show to deliver consistently on quality during its sophomore outing. But its return is still welcome, because the “Baywatch Nights” plot rehashes on “North Shore” weren’t exactly anchoring the network’s dramatic output. The “OC”‘s move to an earlier time slot suggests a courting of the youth vote. And this season’s addition of a Peach Pit-style hangout (sort of predicted here) should unleash a hilariously blatant torrent of Franz Ferdanistic and Killersian guest shots. But since that’s the way it’s gonna be, I hope Le Tigre’s Universal contract stipulates a makeout session between Kathleen Hannah and Julie Cooper Nichol.
