Only to critics. It had a 15 million dollar budget and made 46 million worldwide, which means it made money but not very much. So it's a cult movie. Compare that to another cult movie, the Rocky Horror Picture Show which had a 1 million dollar budget and has made 113 million plus. or compare it to another cult comedy, Blazing Saddles which had a budget of less than 3 million and made 119 million. Those are movies actual people love. The Big Lebowski is good for a few memes and not much else.
It is a great movie and had it actually offended somebody or everybody in the audience it might have gotten more distribution. A movie about some guy who can the sunlight in the middle of storm at night is genius.
