Oscar Wilde: foppish aesthete. Limp-wristed intelligence with prepared wit, language so ethereal that it's like being smothered in a bed of marshmallow clouds. Famous book: Picture of Dorian Gray, about a man who sells his soul to stay forever young and debauch.
Will Self took that and has written a novel inspired by Picture of Dorian Gray, about drug use, gay sex, and ... well, actually, I never got to the point where the plot starts. By page 50, I was still struggling my way through hard jagged language and in-your-face amoral and immoral unpleasantness. It feels wrong to say this, like I'm some tut-tutting septuagenarian who thought they were getting a Victorian novel, but it's not the drug use and gay sex that I object to: no problem with that in other stories. It's the fact that that everything is deliberately unpleasant--in your face, sharp and ugly, not to be liked. You can't like the characters, you can't like what they do nor why they do it, and you probably won't even like the vacuous upper-crust-meets-low-drug-culture worlds they flit through.
Life's too short to be yelled at. And that's what this feels like: like Self has you pigeonholed at the bar and is reading you the poem he wrote after an unpleasant divorce, the one that starts "fuck you with a spade, you dog-faced bitch" and goes downhill from there.
Back to the library it goes, with no remorse.
