You don't have to be familiar with; or even like, the artist to find something meaningful in this movie, nor have familiarity with his works to find fascination within the confines of its premise. This movie asks a fundamental question, what is art? Then drops the viewer down a rabbit hole of what can often be a confusing kaleidoscope of ideas. The very act of determining meaning, validity and depth of purpose from these portrayed pieces is in itself a kind of interpretive dance, which alone defines the feelings felt by the artists audiences the world over. It begets controversy, which is itself a catalyst for conversation. Either way, these acts portrayed created a wave of phycological movement that inspired many, even if only to ask such fundamental questions as: "what is art?"
No matter if you find the acts depicted to be art, or just demented physically realized fever dreams worthy of no more thought than that of acts performed by inhabitants in your local asylum, you should at least be entertained, and at most inspired to think.
