You all should watch it.
Yeah I've always loved the movie, it is one of those movies where I had high expections (because of the praise I had heard) and it still managed to surpass my expections.
I love many other Coen brothers movies as well like Fargo and Arizona Baby (see them too if you haven't). Arizona Baby was the first movie I saw from them and it really blew me away as I was expecting some run-of-the-mill romantic comedy or family movie. O Brother Where Art Thou I liked less, it didn't have the same impact on me. Maybe I didn't like George Clooney on the lead that much.
I had one former girlfriend who didn't like The Big Lebowski though, she complained The Dude was "trying to be too cool" or something. Maybe she was annoyed the movie made a bit of fun of upper class people too, as to me she was a bit of a upperclass wannabe snobbitybobbity, refusing to live anywhere but in more expensive areas of the town, collecting lots of shoes (she had a wall full of shoes; now I can understand someone collecting old video games, but SHOES? THEY STINK! I mean some arab threw a shoe at George Bush Jr, you didn't see him throwing a Super Mario Bros cartridge at Bush) etc.
No wonder she is an ex.
