I've been trying to wrap my head around how Blockchain is supposed to revolutionize the world apart from Bitcoin.
I'm not quite believing you

as I'm pretty sure that you can imagine some applications or areas where the use of blockchain would improve key functions. You just need to have a look at where transactions (in general) are used in our daily life and I don't just mean money based transaction, I'm mean people interacting in any shape or form.
It's a bit like the time before mobile phones or rather mobile communication. In the beginning, people would also say that they can imagine that much of a benefit if you're able to communicate mobile as there where landline phones. Now have a look at how things have changed and how society has adopted this form of communication.
So I think that you don't need a documentary that explains blockchain. You only need some imagination
