[Baby Lee]

Kind of an oddly ironic critique, I think you'll find by the end.
Don't want to spoil too much, but I think you'll find a lot of the complaints you have play into why the narrative is happening at all.
It's not earth shattering, when all is summed up. I don't think I was as disaffected by this as you were at the point you're at. But while I too found the character a self-absorbed bit of a pill, it was still amusing to watch in an anthropological sense. I enjoy plenty of stories even when I don't like the characters in a realistic sense. Doesn't even have to be anti-heroes or even outright villians [Sopranos, Breaking Bad]. Most Woody Allen characters would strain even the most placid and longsuffering of friendships.

But even if you end up disliking the entire thing, I don't think you'll have the exact same critique in the end.
