Overrated for sure and not one of the Cohen bros best. It's got some funny scenes but hard to sit through.
Lebowski has interesting characters but no plot. Nothing ever gets done other than he gets laid and sires offspring. There are some funny scenes but I like to see something get done when I watch a movie. Great quips though.
The big Lebowski's only redeeming quality is the Jesus. I love most Cohen brothers movies. Couldn't get into this one. The bowling alley is actually all I remember from it.
