Book one is too long. Took me ages and I lost interest. In book two, things speed up. Tengo and Aomame finally start to do something. The Little People, the air chrysalis, "real life" maza and its "mirror" dohta, the strange Eri-Fuka... finally things started to happen.
I'm definitely no fan anymore of Murakami's main characters. Always the same introvert guys. The same silent girls. Cooking. Jazz and classical musical. Merf.
What struck me: in book 2 or 3 he for once suddenly switches to omniscient storyteller, instead of the usual limited third person. He does it once, for a few paragraphs, a page at most. Curious.
All in all enjoyable, but way too long.
