Yeah, I read through that trilogy, and the third book in particular really took it to a point of "flawed people fail to rise above their flaws; the future of the human race is wizards eating each other forever". Which, okay, is a valid story. Tragedy is a genre. It's just not really where I hoped the story was going.
Everybody seems to love those books, and I can recognize their high quality - but they're so depressing. God, the ending just gutted me.
