I have been intrigued by the filmography of the Coen brothers lately. Admittedly, I have not seen the vast majority of their work with the exception of No Country for Old Men and the only reason I saw that was because it was such a talked about movie and a box office hit so I had to check it out.
However, they have more than 20+ films in their filmography and I don't know where to start. I like the dark and realism that their films depict so for any of you that have explored their work, which of their films are absolute must-watch?
