Do you guys feel GOT has lost its mystery?

I feel like a lot of what made Season 1 good was trying to figure out just what the hell was going on. Like, there was a "who killed the prior hand" thing; who pushed Bran down; what are Tyrion, Littlefinger, and Varys's motives?

Now it doesnt really seem like that is there. There are still surprises, like how sacrificing the daughter is gonna help Stannis, but the mystery is gone. Arya is learning to kill people, Stannis is gonna fight the flaying people, Jon has all these wildings to fight the zombies, ok cool. But it feels like now...we're just going through the motions.

Idk. thoughts?
