Senza confini

As a Briton, I knew very little about Magellan.

Historic details I don't know in detail. The dirt and squalor of the time look realistic. The smallness of the cannons, and a ship being steered with a lever in the middle of the ship. Things that go against expectations.

The series could have had less on details of the suffering on the later parts of the voyage. And as others say, it was not a profitable route at the time, given the vastness of the Pacific.
