I think the way they did the Baelish scene in this episode was great. I loved his utter surprise, his last, sniveling attempts at worming his way out, and the way Sansa coldly turns his latest advice back on him as he falls to his knees and begs.
The build up to it wasn't great at all, and that kind of dulls it for me. The Sansa/Arya arc was excruciating and uninteresting, and this doesn't make it all better; there were other ways to get to the same point. For example, Baelish gets some legitimate blows in. Or, the viewer knows Sansa/Arya are onto him and we join in as they watch him go to work, blissfully unaware that he's been made.
The Gilly thing...it's not so much the name-dropping. I thought they were really going somewhere with that crucial piece of information seemingly slipping through everyone's nets. It's the kind of thing that should spawn some pretty spicy new drama that then has to be resolved. Instead, it just turns out it was never a near miss to begin with. The things that look like juicy moments ... aren't, because they were really just reveals.
So I think this portends a show that, like this season, isn't very interested in spinning up and exploring new drama. There are still some, though -- namely, the Jaime/Cersei split.
