I've noticed Red Desert to be a favorite on here. I think it's brilliant, but I can't say I personally enjoy it as much as some of the users who have posted here (atyawnicpark was a huge fan I believe). I think Antonioni's masterpiece is L'eclisse... and I probably enjoy Identification of a Woman more than Red Desert as well.
Regardless, that still says a lot because I think RD is great. All of that grayness and fog throughout the film is very symbolic to me. The work of Antonioni/Vitti usually touches me in a special way (emotionally, pervs).
