Best Supporting Actress 2013: Jennifer Lawrence - American Hustle

I remember one thing going through my mind, while I was watching American Hustle. If this film doesn't deserve Oscar nominees in all acting categories, then I can't imagine another film that does. I mean, the film itself really is a mess and you don't care about the storyline. But I loved watching it, because the actors are so much enjoying their work that it's unbelievable.
Jennifer Lawrence plays a wife (Rosalyn) of the leading character played by Christian Bale. The first thing I need to say is that just like almost everybody else in the film, she's a miscast. This is a very strange situation when all of the actors are wonderfully playing the characters that are against their type. Lawrence is a young actress that is enjoying herself and has no worries. But her has more problems that are usual in random marriage and an actress should be a bit older for such part.
Her marriage is about fights and sex. Her husband is a con man. She used to be a single mother. Her husband is cheating on her. But she's a self-aware woman, who can fight for what she wants and who can find her way to enjoy life. She's also a bit rotten, because in fact she's using her husband and she manipulated him.
Everyone keeps saying that this performances is not good enough, because she never became that person. I agree about that, that's for sure. But I have to argue. She was cast badly. How could she really became a worried and an older woman, when she's never lived through such situation? She can't even imagine, she's a carefree actress at the top of her career. This is a part for an older and more experienced woman. And what everyone takes for granted is the fact, that Lawrence handled this inappropriate part with such ease and energy that you can't resist her. I mean, she really gave everything into her performance. Maybe her effort is visible, but she's not the one, who's to blame here.
There is almost an iconic scene in the bathroom, in which Amy Adams's character touches her weakest part as she finally tells Rosalyn how rotten she is. This scene has such strength, as Lawrence finds to way to hurt the other person even more than she was hurt. That's what she does again o her husband. She starts to cheat on him. Not because she would want to, but because she wants to give it to him back.
So everything that is wrong about this performance is not Lawrence's fault. There's either the casting director or the director to blame. And therefore we should not malign her performance...
The chances of winning an Oscar: It is a fight between her and Nyong'o. And though she's second and though a second consecutive Oscar would rather harm her career, she would be the more deserving one...
