95% of The Brothers Karamazov is near-flawless, brilliantly nightmarish reading. The 5% that isn't is the chapter The Grand Inquisitor. I get some parts of it, but when I first read it I didn't understand at all. I plan on reading it again, maybe I'll appreciate it then, but until now, have the product of my frustration!
I think that I just didn't like it because Ivan said it was a Poem, and that chapter was... not a poem.
