This docu-drama is a bit of a tickle, and will certainly entertain hockey fans who are prepared to "suspend their disbelief." Its a nice period piece, and has some wayback footage and dress etc. But when it comes to the actual hockey, which is undeniably central, it comes up short. Everything from the quality of play to the look of the boards is unconvincing. The actors do look a bit like their characters, but its often hard to tell a Mahovlich from a Lapointe. This doesn't really compare to another (excellent) CBC hockey docu-drama, Net Worth, but that movie was focused much more on the off-ice plot (not that it didn't do a fantastic job with its hockey sequences.) And this movie simply doesn't compare to the hockey footage in The Rocket.
Think of it as a "greatest hits" of the series. The writers have patched together all of the best vignettes and anecdotes from the now voluminous sources and reminiscences on the series, so that you get all of the interesting stuff in one mini-series.
For the old time hockey fan, its time well wasted.
But, the greatest liberty, indeed, a downright fabrication, is the end. I will spoil it because its simply not true. The movie ends with the Canadian players returning to the ice in a darkened and empty Luzhiniki Sports Palace, to have a silent and contemplative final beer. Nothing of the sort happened. From my reading, the best I can tell is that Gary Bergman alone did that, right after the game, pausing to (as he said) take in that "old barn" one last time. The other players were chugging beers in the dressing room!
