Atonal music / serialism is insufferable pretentious bs that no one has ever listened to with pleasure, ever. It's a purely mathematical study, orthogonal to art.
I don't disagree regarding "listened to with pleasure" and I only remember actively listening to atonal music as part of a required syllabus. I do think it's perhaps a useful lens to use to look at 'traditional' tonal music through however, even if just to re-affirm that _some_ kind of order and structure is an important part in making something palatable to the ears (or the brain).
