This film must have been made by committee. No one cared about it, I'm certain. It misrepresents itself, firstly, as an authority on Soviet musicals. When there's almost no Soviet musicals in it! For all practical purposes, it's only about East Germany after WWII. Not only is the extensive and mind-bending phenomenon of the post-WWII Soviet musical not present. At one point in this documentary the narrator says something like: there were no Soviet musicals after the 60's! The interviewees have almost nothing to say. The musicals that are there, are not in anyway well-represented. Wait for the real documentary. This simply isn't it.
