I've seen two recommendations for "The Big Lebowski" so far. I'm going to go ahead and recommend you not to watch it. Movie isn't terrible, but it's extremely average - one of the most average movies I've ever seen, actually - and really not worth your time. I think most of the people who recommend it today do so because of nostalgia. Although it is possible that standards were so low in the early 90s that the movie was considered "good" (though not good enough to actually recommend it over other movies).
