Rachel McAdams' performance in Are You There, God? It's Me, Margaret is fine as far as it goes. As Barbara Simon, the mother of Abby Ryder Fortson's titular character, she radiates calmness, caring, focus, fortitude. Which is all she's been asked to do. It's not an attention-seeking performance, and it certainly isn't an end-of-the-year thing. A lot of people have lost their composure over this film, jumping up and down and insisting upon its greatness. To put it as mildly as possible, they're embarassing themselves. It's a nice little movie, but let it go.
