Query: wow

I knew the movie was dark and watched this anyways. I was glued to it from start to finish, even though it seemed wierd at times, and I didn't understand parts of it. I had to go online and google "The black swan meaning." Awesome, convincing performance by Natalie Portman. As the movie unravelled more and more, I wondered what would happen next. The ballet performances were also neat to watch, but the plot is really what made me wondering what would happen next. What a movie, will be thinking and talking about it for awhile!
