I finally caught up with the season. I admit it sort of lost me about half way through. Coming after Game of Thrones, Treme just seemed dull in comparison. I loved Season 1, but much of what I loved about it was different this season. Creighton was no longer on the show, and I couldn't force myself to get into Toni's investigation or their daughter's storyline. Albert was stuck being grumpy for being grumpy's sake and took a back seat to Delmond. I wasn't liking Davis' storyline. Davis was only tolerable when he was there to cheer up Jeanette, and I didn't really buy his relationship with Annie. LaDonna's storyline was kind of one-note. Sonny has never been my favorite character. And the restaurant scenes didn't seem to go anywhere. The only stuff I did like was Antoine and his band.
But I'm glad I stuck around and the season really came together towards the end. Some highlights include Coulson's storyline, Annie and Harley, Albert jamming with Delmond, LaDonna and her husband's decision to move back to the city, Sonny's redemption, Davis realizing he was losing his band, Antoine and the kids, Toni and her daughter's moments in the finale, and many more. The finale was beautifully done and incredibly moving.
I didn't really get Nelson's storyline and still don't - he just seemed so disconnected from everything else. I don't even know if they plan on bringing the character back for next season.
Also interesting to note that in this season of Treme, they brought the police department, dock workers, politics, and education into play. This show is getting more and more like The Wire. :)
