Probably not objectively the worst movie I've seen, but Enemy at the Gates has been taken so literally by so many historically illiterate people that I've grown a burning hatred for the movie for basically slandering the entire Red Army and a few real people who were characters in the story. Kay and Skittles has a really good video on just how bad it is even beyond the "every other person gets a rifle" and "barrier troops gunning down retreating soldiers" shit.
