Just finished watching it, and for anyone wondering who already watched Of Miracles and Men (http://trakt.tv/movies/of-miracles-and-men):

The first third of this documentary feels very rushed, mainly because it covers almost everything already that was handled in the OMaM documentary, but with way less detail, especially regarding Tarasov and his coaching style/relationships. After the first third the documentary slows down a little when they go a little bit into more detail of Tikhinov's style. After about half the time I felt like the new stuff kept coming, which I wasn't too familiar with yet from the OMaM documentary. The last third is heavily focused on the defection and the time in the NHL, which was not at all covered in the OMaM movie.

So at the beginning I was a bit bored because I knew most of it to a greater detail than depicted in the documentary and some scenes were re-used 1:1, but after about half of the movie a lot of new stuff was shown, which I didn't see before. Overall, this one feels a little bit more superficial, but on the other hand it covers a longer time span and parts which aren't even touched in the OMaM documentary, so it's still worth a watch!
