You didn't ask me, but I absolutely hated the main character in Prince of Nothing. I liked the world, and the supporting characters, and if they had been the main characters it would have been awesome. But the main dude just ruined it for me. I won't go into details to spoil anything, but not only had he practiced "seeing all possible outcomes" and reading people's emotions and manipulating them to the point where they were essentially godlike, but apparently he could dodge/deflect/grab arrows, master anyone in combat, etc...I just hated him to no end. His only real weakness was that he was a terrible fucking character. Even people that hated him, couldn't help but love him, blah blah. Fuck that fucking guy. Ruined the series for me, and I'll never read another one.
If you've seen BBC Sherlock (or RDJ Sherlock I suppose too), take that and then add in physical supremacy, mental manipulation, etc. and then multiply it by 1000. That's this fucking guy. Slightly annoying but interesting when Sherlock does it, particularly because he still has some humanity and weakness, and can be wrong. When this guy does it, he's never wrong, never weak, never human.
Sorry. I try to avoid commenting on these books for exactly this reason. It may be irrational hatred on my part, as I know tons of people love them. But I wanted him to die more than I ever wanted Joffrey to die. At least Joffrey is understandable, even if he's a prick.
