Years earlier there was “The Great Locomotive Chase” and “The Hunley” - neither potentials for the Oscar, but both interesting treatments of their respective subjects, and both respectful of both sides of the war.
If there is a movie that fits Shadowstrike’s prescription I don’t know what it is. Josie Wales stands as the most revisionist treatment I’ve seen (FTR: I still liked the movie in spite of their flight of fancy).
Even television shows manage to throw in a back handed slap in every other episode.
I'd give examples, but I'm sicker than a dog right ow, and can't find my notebook (yes, I actually keep/kept a notebook by my chair for things like this)
