Answer: There is a lot of intrigue. Are the Colonists actually friends or enemies of the Native Anericans? Why did The Americans ambush Smith and his party? And the heroic actions on the part of Pocahontas to save Smith by putting her head down next to his to prevent him from being clubbed to death makes for a powerful image.
Explanation: The story has its origins in two different accounts by John Smith. The popular Disney cartoon draws some infromation from the accounts, but strays from history to have Pocahontas and Smith marry. That is NOT true! But it makes for a nice romantic ending to a story that makes John Smith look like a charming guy. In real life, he was not.
