As a footnote, that documentary is oddly structured in that it's about hockey history of course, but also since it is Canadian produced, it does focus a fair amount on how Hockey was influencing Canada/Canadian history as well, hence the "A People's History" part. Still though, I think you'd really like it.
If you're looking for a more recent hockey game to watch or something, it's easy to recommend the Gold Medal Game from the 2010 Olympics.
Definitely looks like something id like yeah thanks, bookmarked that game too cheers
