I can't get enough of this show. I watched the penultimate episode of the season and should have gone to bed, but I just had to finish out the season and watch the last episode. This season veered a little back towards conventional television -- stuff like Colvin's tour of the Western for Carcetti just happening to be on the same day as a police/community meeting was a little bit of a stretch. And it probably had the most obviously happy ending of any of the seasons so far. But there's was so much going on, I forgave them that. And, oh, the drama! And the betrayals! And the redemptions! I can't wait to start watching the next season.
