Some context to start with: I had the chance to see this doc at an exclusive preview session so who knows if it was the final cut. In my opinion it should be since this was a great "tour de force" covering a hot topic full of history and interesting characters.
The chapters build upon each other nicely, the narrator keeps everything well in check, especially if some of the figures in the movie start ranting. Funny as well!
So yah, if you want to learn about that hype around blockchains, cryptocurrencies / Bitcoin and some really grand ideas for the future, those 80something minutes are well invested time. Also superior to going down the online rabbitthole which is particularly deep and confusing on those topics. And clearly less fun.
