(4 out of 4) I remember the first time I watched this, I didn't know what to think of it. The title character, Llewyn Davis, is a jerk at times and that character can turn-off many people. I think I see where I went wrong in the past after a recent rewatch. I think it's important to realize the style and humor of a Coen Bros. movie, which (like many great artists) is distinctive and unlike what others are doing. You don't approach a Coen brothers film like you would a typical mainstream film that advertises itself as a drama/comedy mix. It's important to really get on their wavelength to better understand what they are doing. With that said, this may very well be a masterpiece. The performances, the cinematography, the design, and of course the music all come together seamlessly to form a work of art that somehow blends all of these elements together perfectly. The Coens' have a unique way of blending comedy with drama and that talent truly shines here. I still haven't seen all of their work, but of all i've seen from them, this is the most mature. This film centers in on the struggle to become successful and the world constantly not giving you any breaks. While it realizes that this experience of achieving success is unpleasant in many forms for some people, it embraces people who are on that journey and strive to become what they want to be. Not everyone that wants to be successful will achieve it, but the film is about that experience of putting your passions before your well-being. It's a honest truth that not many films delve into, plus it's not sympathetic and doesn't promise a happy ending, but It's honest, and completely engaging.
P.S. If you have an interest in checking out the works of the Coen brothers, I strongly recommend checking out some of their other work before this one. I think some of their more accessible films might help you have a better appreciation and understanding for this film once you have an idea of the Coen style. I recommend seeing The Big Lebowski or Fargo first. I feel one of those films are better introduction to the Coen's style.
