Sally Jane Black’s review published on Letterboxd:
Bunuel looks like he's having a good time with this one. From what I've seen of his work, it seems like he's either teetering on the verge of complete obfuscation or beating the audience over the head. This falls into the latter category. Though this sometimes works for him (see Viridiana), sometimes, like El, it seems a bit too blunt. Here it's closer to the latter than the former, though the absurdity of the film makes it easier to take.
I cannot fathom how this got made in 1930 in any country. References to de Sade and orgies, scathing distaste for church, the upper class, and more or less everything else, and dirty, dirty sex all feature prominently. It's a wonder not just that Bunuel managed to get this past the censors, but that he had a career to follow it. It was, of course, controversial.
I admire the controversy and the madness. Even when Bunuel is being outright crude, he's doing so with evident passion and flair.
December count: 53/100.
