Besides The Cremator, I'm also pleased to see Buñuel being considered in such high regard. In its entirety, however, his "Mexican" work is relatively uneven. If there's a Los olvidados, then there's also a Gran Casino; if there's a El ángel exterminador, then we also have, by his standards, mediocrities like A Woman Without Love and The Brute. I think Susana is underrated, though, and I'm glad you liked it.
