Once upon a time, Zooey Deschanel was the quirky girl that everybody seemed to love. Now, she's still a quirky girl, but everybody seems to hate her. Confusingly, nobody seems to be able to give a definitive reason as to why. It's been said that the 'New Girl' star plays effectively the same character in every show or movie she appears in - and that character is the unrealistic 'Manic Pixie Dream Girl' trope. Other people feel that her quirks seem forced, and she comes off as insincere.
Deschanel is definitely eccentric - and we can see how her perkiness could become annoying if someone was exposed to it long term - but she has been diagnosed with ADHD, so the quirks are probably real. We've looked everywhere, and we can't find solid evidence of anything that Deschanel has ever done wrong. She's never been arrested, never publicly been mean to anybody, and generally seems to be genuinely lovely. She also supports the Alzheimer's Association and 'Stand Up to Cancer.' Can we go back to loving her again, please?
