Roman Polanski's genre-defining masterpiece Chinatown is almost inarguably one of the greatest movies ever made: a flawless epic featuring Jack Nicholson, Faye Dunaway, and John Huston all at the top of their game, with a screenplay that  is often held up as the best that Hollywood has ever produced - we still feel its influence on modern film, in everything from Blade Runner to Detective Pikachu...but it has also become shorthand for what is now a central problem for film fandom: in the social media era, how do we deal with a great work of art that were made by someone who's done awful things? As you might expect, MG has no shortage of opinions on this!
