I shall refrain from telling my boss your opinions. LOL
True, if you want to get that raise or promotion someday, you'd better get busy watching it. It's not great, IMO, but it's not torture. And a lot of people really do like it.
You could go the boss one better and watch all the Coen brothers' movies and say, "Yeah, TBL was OK but I much preferred 'No Country for Old Men' or 'A Serious Man' or 'Raising Arizona' or 'Brother Where Art Thou' or ..." etc. But that probably won't get you the promotion, either.
I think TBL is kind of a bro movie. Like "Caddyshack" or Adam Sandler movies, except for more highbrow bros. Highbros! And probably also a good amount of high bros!
My son, the one who majored in Media Arts and Culture, wrote his senior thesis about the nuanced subtextual philosophies in "No Country for Old Men" and "A Serious Man." The paper was really good -- kind of like those old posts deeply analyzing BBM -- and made me appreciate both movies even more. But from my recollection of "The Big Lebowski," it would not have been a great addition to the discussion.
