Found it pretty annoying myself. Interesting comparisons to certain events in Fletchers' "there is a light that never goes out' though.
I think the ending is key to the work... The promise of a 'meaningful conclusion' to the novel (I think) Littell is saying is something of an obscenity, something inappropriate. He's playing about with readers expectations about what they can take from such a work. To end in such a fragmentary/ridiculous/laughable way is entirely appropriate. The end replicates the kind of truth of what he has done, which is to say, it eludes anything like 'meaning'.As for the kindly ones. it is brilliant, obscene and infuriating. Falls to pieces a bit towards the end unfortunately, but I think he'd said everything he need to say by then.
