Re: ballet. It's overly formal to the point that creativity is effectively stifled for both choreographer and dancer. It's bad for the body. It imposes stereotypical gender roles on the dancers. It imposes an ideal of physical beauty that is grueling, especially for the women, and inflexible. There's probably more, but those are the things that spring to mind immediately.
