Not read any of the others and not a fan of McEwan but the McEwans I've read have always had a postmodern, self-referential thing going on with them. In fact that's what is often most infuriating about them.
A bit like Ishiguro, actually. Writing about the real world but almost always through an unreliable/subjective lens that calls attention to the dishonest business of telling stories.
The master of this – what would you call it: 'qualified realism'? – (and Luka's favourite author) is surely (luka's favourite author and 'hero') Philip Roth.
I read a bit of 'Middlemarch' last year (the same bit that most people probably manage before they subconsciously decide that life's too short – no that's unfair, it is brillaint, but can't it be released in fragments and delivered to my solitary confinement cell?) and it was really jarring to have this realist narrative with a narrator who constantly tells you exactly what they think of such and such a character and uses the events in the narrative as a springboard for various philosophical disquisitions
