I thought The Leftovers got off to a good start, and it's flagged for me since (the preacher episode most of all), but last week was pretty good. I'm not sure about the whole opening bit with the hooker, but I thought it was a good exploration of their world: the conspiracy theorists, the opportunists, etc. It's OK. I'm gonna stick it out through this season, but I doubt I'm going to be back for the next one. I like the concept, but I don't think the writing's strong enough to carry it.
Halt and Catch Fire is really good. And you're probably not gonna have to worry about a second season, because only about 50 people watched it.
