I mean magical realism is sort of inherently absurd, that's the point of it. You can't really play straight with a grounded, realistic world while simultaneously introducing some fantastical, mythical, or otherwise supernatural elements.

It sounds like you just don't care for magical realism as a whole which is fine, but I don't think there's too much more to it than you simply don't like what the genre entails. Master and the Margarita is one of my favorite books, a prime example of magical realism.... And also is theatrically absurd because again that's the main crux of the genre aside from a plethora of social/cultural/political critiques. The magical aspect is purposely absurd to contrast against the realism.
