I tend to give Murakami more leeway to be crude than other authors, because he sort of uses it as a way to explore humanity and develop characters. 
But this one felt [moreso than what's normal for his novels] anti-climactic for a long and repetitive buildup.
I really like the idea of 1Q84 and two moons, and I was super into the first book of the three- but as it went on I think it should have been edited a lot more. 
This book includes all of the Murakami-esque tropes and devices: some dreamy and ethereal, and some really gross. 

I think I like Aomame? I know I don't like Tengo. Both of these opinions seem contrary to what I've seen in some other reviews but one thing I definitely agree with the consensus on is that the book is a bit too long. And I finished with far more questions than answers. 

I do love when there's something he wants to add to the plot but it doesn't make any logical sense, so he does it anyway and convinces you by giving the main character a profoundly deep conviction about it. Like, this doesn't make sense but we're not gonna explain it at all-- you just gotta trust it because the main character is 110% sure it happened exactly like that. 
I also really like the idea that the weird sentiments that we get moment to moment and think about later in life might be shared. The fate-like connections are fun to entertain. 

Murakami likes to leave a lot of interpretation up to his readers, and likes to play with bizarre & taboo thoughts and feelings and dreams. He has a way of making normal things seem significant and writing super weird things as if they're completely mundane. 1Q84 has that same atmosphere, which I like, but I think I got the ick a little with this one and that was hard to ignore. The plot also sort of fell off at a certain point and it seemed like things wrapped up in a quick way without much interest, especially for such a long book. 

I want to say that after finishing this it'll make me ponder parallel worlds and whatever the heck the little people are supposed to represent, and the morality of lying about ghostwriting, and whether serial killing is wrong if you're killing people like Leader... but honestly I kinda don't feel much at the end. I did like the experience but it's not my favorite Murakami novel and I'm glad it's not the first one I read by him.
I still don't understand what an air chrysalis is and I do wish I could read that book.
