This is .. odd. xD
I'm currently reading Martin's A Song of Ice and Fire series right now.
I don't entirely agree that his character's are neither good nor evil.
I shall try not to spoil it, for any whom might want to read it in the future.
I find myself... loving and disliking the series at the same time.
Mostly because when it comes to fantasy, I'm used to a certain style of.. plot and writing. This is different in comparison. Which is one of the reasons why I both love and dislike it.
I personally wouldn't compare them too much; because they are different. So, to really gauge whether or not it is good, I suggest taking a read perhaps if you can.
