I have it on my kindle because it looked interesting, but haven't read it. And with your comments, I probably won't at this point.
But I hope it gets better for you!
I'm about 25% of the way through it so far, and I'm still kind of "eh" about it. It is SO overwritten. I'm feeling very much like the first reviewer off of Goodreads (which doesn't contain any plot spoilers, just writing style critique):
You know that fashion rule where, before you leave the house, you're supposed to quickly turn to a mirror and then take off the first accessory that catches your eye? Well, I feel like Chabon should have done that with his prose, which is sometimes so ridiculously overwritten and boastful that it ruined an otherwise pretty interesting story.
With some writers, I want them to put on another accessory or two--please, would some bangle bracelets kill you?--but with Chabon I'm like, Dude, before you show yourself to the world, could you please take off that top hat, and maybe that feather boa, and maybe that fake moustache, too? I'm not enjoying your outfit any longer; I'm merely distracted, and annoyed. Sometimes you don't need to describe the sky five different ways.
