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.
So I'm a little late to the party here but in a weird way, I both love and hate it. While it's in some ways his most brutal and repulsive novel, I was actually pleased that I could be put off by writing alone, which is something that hadn't happened to me before reading it. Needless to say, Welsh is my favorite author.
