For the time this film is set, which is 1528, that's a very early era of western exploration (only 36 years after Columbus). I personally would love to see the Americas (North and South) before the full arrival of Europeans. Not because Europeans were "bad" but simply to see something before it's changed dramatically. Unfortunately for many of the early explorers and visitors -- English and Spanish -- a trip to the New World didn't give a feeling of wonder but of life in hell. I'm also aware of the fact that most extant written history of exploration of the New World was written by English authors so it's probably: bad Spanish explorers, good English explorers. But apparently not for this particular story.
As for this film I can only recommend its first hour, which is its best.
The first hour of this film does an excellent job of showing the problems these early explorers faced and how something so promising could turn so bad. Once Alvar Núñez Cabeza de Vaca (a copy and paste on that name!) leaves Florida it loses its sense of adventure and mystery (well a good part of it) and the film moves too quickly from Florida to the western shore of Mexico. So quickly you'd think Florida had mountains or terrain that looks like Colorado. The lead character also spends the rest of the time walking about like he fried his brain on drugs. For me, I'm more interested in and want to see and know about the journey and the people on the way.
I would love to talk to these early explorers or see what they saw and I admire them for their courage and sense of adventure, and if they still exist somewhere, how funny it all must seem to them now. Just wait 400+ years and you've got an area with beaches people flock to and Disney World. Does one man's hell eventually becomes another man's vacation spot ?!?!
This film's first hour does surpass all of "Aguirre: The Wrath of God" (1972) but loses something when it turns into a Conquistador "Apocalypse Now" (1979).
If anyone out there knows of any other good films about early exploration of the New World then e-mail me. Thanks.
