I stopped watching this season after the fifth episode. Not because I wasn't loving it; rather, I was watching seasons 1 and 2 with my roommates, and I wanted to watch the rest of this season with them. We're starting season 3 tonight, so we'll have to wait for those last two episodes.
Season 3 has been interesting from what I've seen of it. Season 2 was a lot more serialized (or rather, the back-half of it was), and I thought that gave it a lot of its weight. Season three wasn't quite as good, but I felt that there were some great self-contained episodes, much better than their counterparts in seasons 1 and 2. In fact, outside of The Sopranos, X-Files, and maybe one or two more, I think Justified has been doing these stand-alones better than any other drama I can remember.
