Oh if you care about stuff like that then the next two seasons will be better. MUCH better. People say book 3 is 'fast paced' but it's all walking. In book 4 and 5 there's no walking. Only happening. Like, no one is getting somewhere, everyone has gotten where they are.
Probably the only reason book 4 and 5 feel stretched is it's actually the same book. He just cut it in a way so half the characters are in one book and the other half are in the other book.
