She is my favourite thing about Greys. She is charmless, professionally ruthless, and is never caught selling herself short. I find that in the media, very often women's accomplishments are measured by that of a man's. In the Greys universe, you're measured by Yangs.
She's the smartest, the most determined and most hardworking. She is driven by professional ambition, rather than the stereotypical need for a happy healthy relationship to feel complete. There's been a couple of times where the storyline has had me worried about where they were taking her, like when she was compromising her career to help Burke, but as the series progressed, you saw Christina really take back control of her life.
One of my biggest issues about the battle of the sexes is how men are seen in the media. According to tv, it's important to be manly, and to be manly you need to be a muscly sexual predator, with a good face and a job that's respected, well paid and in a position of authority. Whilst Greys still holds a cast chock full of "beautiful people", Karevs character breaks slightly from the normal behaviour of typically manly guys.
|Still got a nice face..|
A super easy way to sell a tv show or a film is to get a hot person barely clothed in every episode. Or a hot person tightly clothed. Basically any use of the physical appearance of characters to keep viewers coming back in the hopes of getting peeks at these beautiful people and they're beautiful bodies.
So there you have it. Not a grand list, and not exactly one of the forerunners when it comes to breaking down archaic gender roles in the media, but closer than most.
