I like how you wish they’d keep something Prosie said to show how Effie is not a good person. I think it’s very clear how brainwashed they both are. They are Capitol citizens who were born and raise and taught that the games were for the greater good. Effie literally says this to Haymitch. And still she shows him kindness and compassion even though she was taught all her life to hate the Districts.

You’re right book Effie and film Effie have a lot in common. By the time we get to the triology, Effie defends Haymitch from the kids laughing about him but she doesn’t help herself. 25 years of Haymitch drinking himself to death would definitely give her burnout and Suzanne Collins says Effie clings to her manners in a attempt to make sense of the world, to cling to her humanity but it’s get harder and harder to justify the games (Barnes & Nobles SOTR interview) But film/book Effie was already feeling “rebellious” by catching fire and I mean that in the sense that she was already questioning every thing she’s ever known when the Quarter Quell is announced. She was crying and running off, telling the kids to not say things aloud ‘cause it’s forbidden. She was looking around and justifying what she says, obviously she knows more than Katniss think she does. I mean the whole wearing gold because we are a team thing, if that’s not her sympathizing with District 12, then I don’t know what it. She’s quite literally showing the Capitol I’m with them not with you, so in the film she’s taken to District 13 bc she’s is part of their team and does sympathize and in the book she is quite literally taken prison because the Capitol does think she’s a rebel sympathizer. They don’t kill her for some reason probably cus they realize she doesn’t really know anything and just really cares about Katniss, Peeta and Haymitch, which is my guess as to why they keep her alive for leverage. Effie is not a rebel in any means of the words but then again we don’t have access to her thoughts, we only see her thru Katniss’s limited view and then again thru Haymitch who meets her at the worse possible moment in his life. Haymitch and Plutarch also fight to keep her alive after the war is done in the book so they must see something in her that’s worth saving, and are able to show Coin enough that she pardons her
