The show and its main story is alright, nothing more. But the "wall" is great. My first thought when they showed a scene from inside it was "damn, I wish they'd make a whole episode about this". And lo and behold when I got to episode 7 it was just that, and how good was it? It was freaking awesome! For sure the best episode of season 1. I hope they keep spinning on the wall story in season 2.
