Spent the evening at a friend's place getting caught up on The Wire as I lack HBO. I haven't really been reading reviews but from glancing at them I've sensed that there has been disapproval of this season. Or maybe it's just that journalists have disapproved of this season. In any case I think it's pretty good so far.
Try to avoid temptation to put spoilers in comments, aside from the fact that Darth Vader is McNulty's father.
