If as an actor or actress you don't like the character on your show, then I think you should discuss that with the producers, director and writers. That's it. Sure, you might share with your fellow cast members your frustrations, but whatever you do you don't want to become known as the person who is a pain in the ass and complaining to the press.
Unfortunately Chloe Sevigny never got the memo. In an interview with The Onion AV Club, Chloe became Katherine Heigl II, with her blasting of Big Love.
“It was awful this season, as far as I’m concerned. I’m not allowed to say that! [Gasps.] It was very telenovela. I feel like it kind of got away from itself. The whole political campaign seemed to me very farfetched. I mean, I love the show, I love my character, I love the writing, but I felt like they were really pushing it this last season.”
I think the season was not as good as the past, but it wasn't horrible and still better then most other television. The thing is, Chloe was not content in just going down in flames on her own. Nope. She had to take other cast members with her.
“Me and the girls [Jeanne Tripplehorn and Ginnifer Goodwin] definitely were not very happy with where it was going—or more kind of, “We really hope it’s going to work. It seems like they’re really pushing it.”
I haven't heard the “girls” say anything about it. They probably know the best way to accomplish something and not have your character die in a freak accident is to talk to the people who can do something about it. If your job sucks, you don't go telling the world, you tell the people who can do something about it. All Chloe is doing is setting it up so no one will hire her. When there are a million people who want a job acting, why are you going to hire the one that might go stab you in your back. You won't.
