It's innovative, of course it is.
But it's also pure nonsense.
Which I don't have a problem with. I LOVE Kafka, and Lewis Carol. But in those cases there's always a sane character. A guide to the insane world, to show you what it's like. Someone to identify with. There is nothing like that here. It's all nonsense, so loses the dark nihilism it thinks it has.
The black comedy is funny, and the ending landed wonderfully, but all in all... It's just nonsense.
