Buñuel, redux

Dave: Can you give examples of Buñuel's moral sense? From what little I've seen of him (Andalusian Dog, part of The Golden Age, las Hurdes, Viridiana, part of Milky Way, and a long-ago film class viewing of Belle de jour), his moral sense seems to be driven by a cookie-cutter anti-clericalism and an all-consuming need to tweak the bourgeoisie.
