Query: fantastic content!!!

To start off, yes the video quality, production value and dubbing are pretty terrible. That being said, this video is the closest I've found to going to an actual ballet class. Really, the content is great. The barre exercises are cohesive and the music is really nice. I'm not sure if this video would be good for someone without previous ballet instruction as proper technique is only barely touched on in the last 2 minutes of the video, but for someone like me that's looking to supplement classes or be able to take class on my own schedule without having to leave the house, this video is great!
