Sorry i missed it Dude, i know we read this at about the same time.
I also had some mixed feeling about it.
Strangely enough, it reminded me of Foucault pendulum.It involve the same types of guys obsessed with conspiraty, doing sharp researches in small flats with little sleep and hight on cafein, trying to bring dark powers out in the light.
Expect that with Lethem, they also are high on pot and there domain of inquiery is about Marlon Brando super power, holographic chaldrons, association betwin music, dope to open extra visons.
And as in Eco there is a certain amount of self delusion, so have those New yorkers not ever been to sure of their digs. Which in there case seem more obvious for it involve a two storey high tiger in NY, a three legded pit bull with her own flat and a girl friend stranded in space by a chinese field mine.
The main probleme for me was with the ending, where Lethem try to give a certain logic to the all shlibong, he sort of try to justify and relate things which were better left alone and myterious. And to come back to my dubious association with Foulcault, it would have been the same if Eco finished the book in giving credibility to the supernatural powers of evil.
There is a lot of good in Chronic city, and i liked ideas and style, the paradoxal conviction, intensity and the shallowness of the characteres, it's just that a good or a bad ending alway cast a all new light on an entire book. The last chapiter spoiled it for me.
