There is a lot of bad history in movies. Some have nonetheless been great fun, gotten great reviews, even Oscars ( like Peter Shaeffer's Amadeus and recently The Favorite) . One that tried pretty hard to do justice to period language, period setting, and the historical record was Spielberg's Lincoln, where even the actors playing Seward and Staunton actually looked like Seward and Staunton. It also tried to portray something not usually given much attention: when the North refused to compromise with the South, which had offered to stop the war and re-join the Union if it was allowed to continue slavery. It was a political victory, but much more important than most of the actual battles because there was strong popular support in the North for such a compromise. If the compromise had been accepted, slavery would have continued.
