Agree re: Tarkovsky, especially in Rublev, Mirror, Sacrifice and Stalker. Bela Tarr's Werckmeister Harmonies is also a visual feast (someone else mentioned Satantango by Tarr). Reggio with Glass makes eye-food too. On the other hand, Greenaway is so shallow and glib that, to me, all his films look like (and are) a series of vomit puddles.
