Part of the problem is that there is two very clear sides. With GoT you had so many different arcs and families all wanting a slice of the pie. With this it's just a squabble between the two big families and all others are pushed aside as minor houses with bit parts. I was hoping this Season would introduce a few more families to the table but they've just continued with the same two.
I actually don't mind the characters, even Cole is entertainingly wet, without falling into the pantomime villain role. They're all a pretty believable bunch, just I find there's a lack of spark. Or perhaps a lack of wit that the show needs.
Still, next episode looks like a banger, so I imagine people will probably rave about it next week.
