Well this Movie is known only to a fistful of people. Its a real treasure of Italian Cinema and worth more attention. Whoever read the book will see, that it is the perfect adaption. The ones who will understand what book and movie are about, will love this. Personally it is my second favorite Movie of All Time and I'm glad to own the VHS at least.
My rating: 10/10
I guess you can't make a movie like that anymore nowadays, because it is pure art and not like the Computer-Crap now.
Sometimes, a movie (like a Wine) needs time to mature. I think thats why Visconti himself didn't like this Movie that much. I don't know how it must have felt watching it back in 67 in Italy, because its based upon a philosophical literature and the average Man/Woman in Cinema wouldn't understand it without the background.
