I watched all three seasons in about a week. I can't watch them one a week, not for any show, which everyone says is a bit strange.
It took me three episodes to properly get into it. The first episode was incredibly slow, and then the second one hurtled past. After that, it was amazing. The acting, settings and everything are amazing.
I didn't find the wedding as shocking as everyone else did but I think it's because my expectations were raised so high for the Battle of Blackwater episode and everything hasn't been as good. Probably also because I'm beginning to think (and I think they showed with the red priestess) it's just everyone fighting and then they'll have to join together to fight the White Walkers until Mother of Dragons shows up.
BUT there has been so many twists and turns I don't think that'll happen. Can't wait for season 4.
