I only remember one thing that I didn't agree with. The narrator at one point said that the whole process doesn't

You still need to trust: your software implementation, the initial block chain you get, the network as a whole.
Sure, the network has excellent abilities to dominate malicious members. But it's still possible to have a large population of malicious nodes, or (far more likely) a software bug with a common implementation.
