It's a joy from beginning to end...a celebration of life & the wonder that is man. To combine many elements of Homer's Odyssey with great music into the rich fabric of the 1930's Depression and wrap it all around such interesting characters is a true leap of imagination. Every character is interesting, not just the 3 leads. Who else but the Cohen Brothers would have ever thought of it.
Like the movie Groundhog Day, this can be watched over & over, getting better each time as the insights and awareness of subtle shading and deeper meaning sink in. I especially recommend reading all the external reviews, all 700+ user comments (the number of which indicate the chord this has struck with people), and the trivia link at this site. These will add greatly to the understanding and appreciation of this fine film. It's rare to have a movie which is so entertaining in it's own right, but which also has such deep meaning.
This movie has legs & staying power & will only grow in stature over time. I predict we'll be talking about it, watching it, and learning from it for decades to come.
