Smith was a grown man and there would have been no rationale for Smith to have a love interest in Pocahontas. But Pocahontas was enthralled by him and probably respected him because of his good nature. Smith in turn was fond of Pocahontas as she might be a daughter. She was the one who always brought baskets of corn to the settlement, and so it would have been easy for him to grow an appreciation for her. Although this is evident, a love interest is not. .
Pocahontas had saved Smith's life, and that would have been an obvious reason for his liking to her. Disney's Pocahontas builds on the rescue, making it the climax of the film; the young heroin risks everything to save the man she cares for. Historically, we already know that Pocahontas didn't even know Smith at the time of the "rescue", never mind care for him.
On the voyage to the new world, Disney depicted a voyage of a pleasant trip. Historically the voyage was rough with constant storms hitting the ship and lasted for an approximate 5 months. While aboard the ship when rations were gone cannibalism had spread throughout the crew in time, causing them to eat each other and other objects. Victuals had been depleted and the crew were about to eat each other to survive. The voyage was so harsh even the higher officials had trouble; in the movie the governor had plenty of food and enjoyed the trip as if it was a luxurious expedition along his pet dog. If that was true, the dog would have been eaten within a little amount of time due to the lack of provisions.
The Disney Movie, "Pocahontas", is accurate in some respects. It captures the spirit of the woman Pocahontas and her people, and the spirit of the early days of Jamestown. The settings are accurate: both James Fort and Powhatan village are portrayed authentically, according to current historical and archaeological knowledge (except that there was no bluff overlooking James Fort).
