It's a well crafted movie. Thrill and suspense are all there. I found it entertaining even though it's about a ballerina.
Now, the main reason why I rented this movie, the scene between Natalie Portman and Mila Kunis, yes, it was good. It's not as real as typical lesbian scene you would get from all over the internet which tells me that neither one of the two are experienced in such thing (fortunately or unfortunately depending on what you are into). I could detect a bit of obvious acting during some parts of that scene. I'm not sure how much of CGI can be help with such action but I think it could have been little bit better. Not a complaint but just a critique.
