Being an alcoholic doesn't excuse being an arsehole. Sure he apologised but that doesn't change the fact that he butchers history. He's talented for sure but he ruins it with what he uses said talent for.
I'm not really mad that he wasn't being realistic and historically accurate, Hollywood usually never is.
I dunno, there's a difference between being 'historically inaccurate' and 'propaganda', and the latter was essentially what
The Patriot was. Fair enough if they want to put it a certain way for American audiences but they took it a bit far lol.
