As a season premier I thought it was a little weak until the end, with Jamie about to go under cover. I would have liked to see a couple of twists in the murder case, I'm guessing with the new mayor they couldn't fit that in.
I wonder how this new mayor & Frank will work out, yes he seems to have respect for what Frank did when he was a child, but they do seem to have different ideas about what right & wrong are, that should prove to be interesting. And it sounds like Jamie's undercover case is going to be a bit dangerous, can't wait to see where they're going with this story line. Looking forward to what looks like is going to be a very intriguing season.
