What makes a cult classic? Does having several annual festivals around the world organised by die-hard fans count? (the London event is known as The Dude Abides). What about spurring a brand new religion inspired by a character? (that's Dudeism, a variant of Taoism). Or reviving the popularity of a cocktail? (ever head of White Russian before 1998?)
Far from being shallow pastiche, it's actually about something: what it means to be a man, to be a friend, and to be a 'hero' for a particular time and place.
