Ha. I'm the opposite. It was the book that put me off Welsh for at least a decade. I'd enjoyed Trainspotting and the Acid House but did not like Marabou Stork. I plodded through as it was before I realised that life is too short to spend reading books you hate.
I found it disturbing and pretentious but I was young and probably stupid.
Glad you enjoyed it, maybe there's more too it than I recall.
