Like the last season, I won't have enough time to cover everything that happens on Treme, but I'll try to hit some key points.
The nature of Treme is that there is not an overarching plot throughout the season, unlike David Simon's The Wire, which carried a singular plot through each season. This was problematic for many people initially, expecting a New Orleans version of The Wire, and the ratings dipped as the season progressed. Still, for those who stuck around and accepted the show for what it is--slices into the lives of certain people in an expansive environment---there was a lot of watch. The characters were firmly established, outside forces pushed and pulled them while they did the same, and we got to see lots of the city and hear the music.
"Accentuate the Positive" follows in the same vein, following a bevy of characters across the country (most are in New Orleans, but Janette and Del are in New York) a bit over half a year since the end of last season. The characters' paths still aren't crossing all the time, but we do see Davis and Annie firmly together while Sonny is still hanging around and seemingly fine about the situation.
As far as things that really caught my eye, Sofia is still struggling in the aftermath of her father's death, and Toni, who has her own problems, can't seem to reach her. It seems like a major element of the second season is the growth of crime, and Colson will be a bigger part of the season in response.
Score: 9.0/10
