I liked the first season. When I came back to season 2... I was struggling through the first episode. So I put it aside and figured I wouldn't watch it. But last week I made it through the first couple episodes (which are slow with a lot of long cut-scenes), and I got hooked again. The action picked up a lot and there were a couple episodes that had me binge right into the next one at 1am. One of those "Come on... you can't leave me hanging like that" -- kind of things.
I could understand how the show would make some people uncomfortable: there is a homosexual (male) couple and a transgender female who has a female partner. But at this point in my life, I am very certain I am heterosexual, and the storyline is really quite interesting. For me, it was a great season, and I cannot wait for the next one. (It's no GoT, but I enjoyed it.)
