Some of the most unlikeable characters in fiction.

I could say a lot about this book but nobody wants to read a novel in review in review.

So I will just say that, in general, the characters in this book are terrible. Well written, well performed, and completely unlikeable.
The main character is a whiney insufferable narcissist who abjectly FAILS for 15 hours straight. The voice in his head is a complete jerk for no reason, even when one is given it makes little sense. Most of the “humor” falls flat, mostly random 1-liners that are more miss than hit, though I did laugh at a few good ones. Most of the other characters are only there to gaslight, manipulate, or crap on the MC. Admittedly he does sometimes deserve it for being a PoS, but 16 straight hours of it gets VERY old.
