This movie stinks. While I appreciate the historical value, the importance was lost by a poorly produced, executed, directed film with poor performances.
A well produced movie tries, at a minimum, to film in locations that look similar to the locations where the real story took place. That helps make the story more believable. I enjoy historically based films that are shot in locations that try at a minimum to appear to be historically correct. John Brown was captured at Harpers Ferry, then Virginia, at the arsenal not a fort.
