Ole Holgersen’s review published on Letterboxd :
Director Luis Bunuel is often described as a surrealist (and so he is), but the word misapplied in reference to his later works, where the the term absurdism is much more appropriate. Such is the case with the The Discreet Charm of the Bourgeoisie.
This is probably one of the most absurd, symbolic and satirical films of all of Luis Bunuel's films. It has many different dream sequences that punctuate the narrative, and in fact, there's a highly complicated "dream within the dream"-sequence that's both funny and mysterious.
The Discreet Charm of the Bourgeoisie wasn't as funny and engaging as my favourite Bunuel-film, The Exterminating Angel (which has many similarities), but is definitely one complex piece of cinema. It's many absurdities and situations makes for an extremely weird film. I guess that without the analysis by Spanish cinema expert Peter Evans that followed on the blu-ray, I wouldn't even be able to understand half of it!
