Given that I can't find anything I really don't like, I'm going to say my vote on plot is 6 of 10 or so. I like the way it was set up, with his childhood, tragedy, Tarbean(? I need my book!) and University experiences leading up to the deepening Chandrian investigation. I think we're getting a solid sense that he believes he does what he needs to do and doesn't make too many insane choices that didn't need to be taken (in his opinion). It's a pretty good set-up for why he would eventually become a king-killer and believe/be able to convince us he had reason. Or something.
