The Fifth Season

What's enjoyable about this? The main characters are constantly negative, moaning, complaining, bickering, spiteful, mean etc. All the time. How this received a Hugo is beyond me. So what if there is some world-building or new races etc, without enjoyable characters and something of value out of it all, what's the point? What did I gain from reading this? Pretty much nothing. Do readers gain value by feeling superior to the absolutely crappy main characters? I suspect so, but not for me thanks. It's not even educational as to that psychology, just crappy.
And, just in the interest of balance. I have read literally thousands of novels, probably 10 times what i can remember to add to Goodreads, and VERY seldom do I read something that is unenjoyable, this is an exception. That it was awarded a Hugo is depressing. The only reason it's not one star is that it is not poorly written edited etc.
