The OC actress Rachel Bilson has bashed the show that made her a star and insists the teen drama has run its course. Bilson, who plays SUMMER ROBERTS on the series, believes four seasons of portraying life in the posh Southern California beach community are enough. The 25-year-old, who dates co-star Adam Brody, says, "I just feel like the show is over. "I'm so happy for everything that it's brought me...but I think we're all ready to move on."
