This is an absolute gem, an unique document about the sport training for contests in Eastern countries, formerly bloodlineed with communism. It is tough, rough, gritty, hard to watch, sometimes, not destined to sissies but so realistic. I love movies speaking of sport, high scale, level sport, the things about which no one never talks about. It is poignant, nasty, gripping, disturbing, far, far from Hollywood fairy tales craps. BLACK SWAN in gymnastics if you prefer. It is an awesome film, believe me, I guess there were not so many of this kind, of this quality. Do not miss it, at any cost. A pure jewel.
