The historical accuracy stuff doesn't grab me too much. I don't expect or want that from the movies. The only character I had any sympathy for in the whole thing was Billy-Bob's Crockett. He shows up to become a pioneer again in the new Texas territory after losing his seat in the Senate, then finds out the fighting isn't over and gets pulled into a losing defense of the Alamo while trying to live up to his fabled image and still provide inspiration to his fellows. THAT's a good plot and conflict, and makes for a good story, whatever the historical accuracy behind it.
