The name of this film is "Who Gets to Call it Art?". A more appropriate title might have been "Who Gets to Call it Art? Henry Geldzahler Does!" or maybe "Henry Geldzahler is Totes Awesome". This movie is relentlessly effusive and congratulatory about Geldzahler's life and work - it feels like an extended version of something you'd play at a banquet thrown in someone's honor, right before giving them a Lifetime Achievement Award.
That said, there's a lot of good stuff in this movie: there's great footage of influential New York artists in their youths along with more-recent interviews, and it provides a decent look at the fabled mid-20th-century New York art scene. It's worth 80 minutes of viewing-time for any art-lover, but it's not a satisfying piece of work.
