-I was happy to see the focus of the case unit back on the Barksdale organization, but now I feel like I did at the end of S1, and a quick glance at the main storyline of S4 does nothing to allay my worries. The school system?

-This mostly just expounds on my doubts about the next 2 seasons, but it seems like they could have wrapped up the whole show this season if they fleshed some minor things out a bit more. I was always hoping that the series would conclude with the downfall of the Barksdale organization, and again, I can't see them coming up with anything that will compare to the intrigue of this season. At the end of the 2nd season you could already see where the plot was headed -- up -- but this time around it seems like it's all downhill from here. Hopefully I'm wrong.
