One of the best parts of the original trilogy was watching West and Ninefingers be brutally beaten down by the nonstop violence and vengeance while still coming out "human" (well, maybe not so much for Ninefingers...). Too many characters in The Heroes seemed to have existed just to be murdered or emotionally destroyed.
I will say one thing the character arcs for the trilogy is seriously the strangest ive ever read where you hate a few of the characters especially that annoying prick one, really love the characters by the second book, and then really hate there actions in the third book. The only consistent one was Glockta I think his name is.
As for the second point kind of feeling a little bit like that with this book where the characters go through a bit to much heart wrenching stuff.
