Is Mischa Ruining Her Own Career?

We thought Mischa Barton was strutting her stuff in Cannes to gear up for a screening of her new movie You and I. Instead, after hanging out at the festival for a few days, she skipped the premiere and headed to London for Britain's Best 2008. Apparently she thought the movie was awful and didn't want to be involved with the promotion. The film is just one a few bombs that Mischa has been part of since The O.C., and while Assassination of a High School President got some love at Sundance, we want to know — do you think Mischa is ruining her own career?
