I was impressed by the realism of this film

Rating: 9/10 (3 April 2017)

I just happened to start watching this movie and was immediately struck by how restrained it was. It didn't go over the top in either direction, either making the historical figures larger than life OR turning them into complete jerks or anti-heroes. It just let them be human beings--not quite average human beings, but human beings nonetheless.
SPOILER ALERT I started reading up on Bowie before the movie reached the point of his death and learned that the movie depicted the most likely scenario, that he died sick in bed trying to defend himself with his pistols. But the film didn't try to turn this into some last stand of blazing glory where he takes out a dozen or more enemy soldiers before falling. Bowie manages to shoot just one or two soldiers before he's overwhelmed and slaughtered.
Crockett's death was probably more dramatized--from what I read it's more likely he died during the battle than from being captured then executed (but not before getting in a couple of digs at Santa Anna). Still, even that scene doesn't overwork the dramatics too much.
