What film, show or game that is not necessarily 'underated' didn't have the level of social impact it deserved.
What's the antithesis of Arrested Development, Firefly or The Big Lebowski? Those may never have 'found their audience' but over time seemed to recognised by everyone. What are the deep cuts that you liked but it feels like everyone has completely forgotten they even existed.
Such a good movie and a great showcase of Steve Carrell's (and the rest of the cast's) range, managing to be heartbreaking and laugh out loud funny throughout the movie.
