Polina Semionova rehearsing La Bayadere under the direction of Vladimir Malakhov. If you wish to see more you need to buy the DVD "Vladimir Malakhov, making of La Bayadere", avaible here: http://www.staatsballett-berlin.de/service/dvd.php3?id_language=2
This is a clip from a video about Vladimir, which is why the camera is focused on him a lot of the time. I understand your frustration though, as I too would rather see all the dancing, as it is so beautiful :)
The filmmaker is clearly more interested in Vladimir than in Polina's dancing which is quite irritating (and insulting) as she is the whole point of this video!
she's amazing.
It was beautiful to watch! And her feet... love it!
Grazie! Roberto.
