Ralph Steadman is one of the greatest, most underappreciated living artists, so it's wonderful that this celebratory documentary has arrived. It also happens to be one of the finest docs ever made about an artist.
The salient, liveliest parts of For No Good Reason - the title comes from Thompson's reply when Steadman once asked him, "Why are we doing this?" - are to be found in the artist's display of his work and recollections of the eccentrics he met.
"For No Good Reason" is less revealing than a standard hourlong television tribute might have been. We learn almost nothing about Mr. Steadman's life, and too little about the non-Thompson-related aspects of his oeuvre.
