The dialogue and exposition in this show is mostly awesome. It's often better and more interesting than the action - though the fight last night was really well done. Probably the only dialogue I find annoying us the red witch or whatever she's called.
Walking Dead follows a similar action:exposition ratio, except the exposition is boring and lame, which is why that show sucks. Without good dialogue, the fighting in GoT would get boring and repetitive, just like Walking Dead.
