When she gets the rich idiot to take her in, she's got shoulder-length hair. He buys her dye. Don't tell me he also gave her that fabulous chin-length haircut.
The question is, did he take her to a salon or did he have a stylist come to the house?
Did you actually watch the film? Amy is obviously quite capable of handling such a thing. Her problems come from an area in life in which she has no experience... Actually living life without the Privilege of who she is. All of her problems come when she is TRYING to live as a Nobody. She assumes it's easy, she's obviously just so much better than her poor little bungalow friend... Ooops. Guess Not. Everything unravels, she literally KILLS to be back in her life of Privilege and Control... So, while she is brilliant in many ways, including a very easy haircut, she's a moron in ACTUAL Life Skills.
Amy's character is stablished as a skilled, resourceful woman who never really had to worry about her job and always spent her time learning new things and dedicating herself to hobbies. I know far less skilled people who can do that haircut by themselves in front of a mirror, so...
Amy unravels when she assumes living amongst us "Regular Folks" will be a Cakewalk for someone with her pedigree. Her entire life is a facade. She is as truthful and real as "Amazing Amy." Raised in Privilege, while the Media portrayed her as a Victim... The real Victims of Society rob her blind, seeing thru her BS. I love those scenes because you may not notice at first but on second viewing, you can tell she was being played from Day One in that Bungalow. She is smart and capable in many ways but being a Real Person isn't one of them. Fincher drilled her type to the Wall... And while he doesn't forgive Nick, he is shown as a Real Person as far as Emotions go, even though he's dishonest, smug and lazy etc.
Great analysis! Funny you mention Nick as "a real person". At the end, Gone Girl is also a story of Nick's dehumanization. A low-functionig sociopath growing into a high-functioning sociopath, like his wife. Nick's experience with media scrutiny and the creation of his fake, public self around the ending is only a taste of the nightmare Amy's childhood was, and only the beggining of the very alienation that made Amy the monster she is. At the end, Amy Dunne got her revenge over her husband by making him rise to her level... of misery.
