One of my favorite characters is tyrion. And jon is also another favorite. Arya rounds out my top three individuall characters. I'm not really a fan of bran not because he himself is a bland character but because his storyline is not the thread I especially like. My personaly favorite storyline (not nessecarily character) is daenarys.

I hate cersei and lady arryn mostly because one is evil and one is a weak mother who raised a weak child.

Characters I like but are imo relatively minor, robb, lady stark, most northmen I like.

Characters I'm ambivalent towards, samwell (hate his cowardice love his kindness) lord lannister (he is in the end a good leader), shocking one probably for you jaime lannister.

Ugh you haven't read so many new developments my development and opinions of the characters is going to be completely different, you have no idea what's going to go down, you say what you like martin ain't afriad to kill his characters off.

As for leviathan I never said it was perfect just that some of its ideas are good. And hobbes writing style is pretty reminiscent of his time for philosophy.
