These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Inside Llewyn Davis
Award Snub: All but ignored at the Academy awards, despite being one of the best received movies of the year.
Hilarious in Hindsight: In the film, Oscar Isaac and Adam Driver sing "Please Mr. Kennedy", a song where the narrator doesn't want to go to space. Since then, they have been confirmed as cast members of Star Wars Episode VII
Ear Worm: Marcus Mumford and Oscar Isaac's rendition of Dink's Song.
Jerkass Woobie: Despite Llewyn's unpleasant personality and antagonism towards seemingly everyone he knows, he is shown to regret many of his failings, and his lack of success or any good luck at all makes him quite sympathetic.
Narm Charm: "Please Mr. Kennedy" is a silly novelty song about manned space flight, featuring stuttering and quirky backing vocals. It is quite entertaining.
Tear Jerker: Llewyn's final rendition of "Fare Thee Well", sung with perhaps the most raw emotions he had shown throughout this movie. And can be interpreted that he has rather woefully moved on since his partner's death. It's a glimmer of light in such a Downer Ending.
