I hate it when people like Perez are saying "her career is going downhill".
What does that even mean anyway?! People are so narrow minded, that they will attribute a 'good career' to being on the OC and being popular. Unfortunately as an actor, you don't always get what roles you want and sometimes you have to do a lot of waiting until you find an interesting project.
I think this is what Mischa is doing. And evenso, Mischa started out in theatre, so who says she has to be popular-culture-tv show-movies, all the time?! Why can't she just...you know...live!
