Well, obviously it's not perfect... The 15th anniversary of The Big Lebowski's 'release' has been celebrated recently, and here is a link to help you enjoy it, courtesy of EW.com.
Personally, I'd've got rid of the parodies. I think they're pretty poor, not that funny, but then I still applaud their spirit. When in dialogue about something as great as a Coen brothers' hit, it's hard not to fall short of the mark, so good on them for trying.
I've been thinking about my favourite song from the film: it's impossible to choose. CCR's 'Lookin' Out My Back Door' is always a strong contender, but often I feel like I relate a lot to Bob Dylan's 'The Man In Me'. The psychedellic vote certainly goes to Kenny Rogers with 'Just Dropped In' (an undeniably great tune), but then what about this, this, this or even this? It's ridiculous, there are so many more to choose from too. Carter Burwell (who has inspired a major character in a short story of mine, yes it's true!) is a bloody great man, another person whose association with the Coen Bros. has helped them to their greatness.
On a side note, I think reducing an entire film to the repetition of a single word is a noteworthy enterprise. It happens twice in EW's selection, on page one (with the word 'dude') and page five (with the word 'fuck'). The rhythmic qualities of doing this create a great performance piece of poetry (perhaps!). My other fave video in this vein includes the Shortened Scarface, I'm sure there are plenty of others. Please don't dismiss it as puerile until you've had a go!
So, what shall we take from this post? That The Big Lebowski is good? Yes. That The Coen Brothers are good? Yes. That the f*** bomb is good? Sometimes. I don't know, take from life what you will. I'm not going to dictate...
