Barney is one of the most famous and critically acclaimed contemporary video/performance artists. He is known for his elaborate, lavish sets and costumes that he designs for his video performances, which resemble Hollywood productions more than independant art films (in terms of quality, not the sets themselves). Barney's work is full of high concept imagery and surreal scenarios that barely reveal any narrative. His work is controvercial within the art world, with some critics accusing him of being all flash and no substance while others have hailed him as one of the greatest living artists.
Personally, I'm still on the fence about whether or not Barney's work is full of the complex symbolism that he claims is there. I watched two parts of the Cremaster Cycle, parts 3 and 5, and they were visually quite stunning. Whether or not they have any depth, I still enjoyed watching. I'd call Barney's work surrealist post-modern video art.
