I love this show. I mean, I really really love it and it's possibly the best stuff to ever grace a TV screen in terms of writing, acting, set design, everything.
But...
I think it probably peaked with the death of Jimmy. Nucky has gone from a Tony Soprano like quasi part hero, part villain, to 100% deplorable villain. And I just don't like the Margaret character enough to get behind her as the primary protagonist. Pardon the wrestling jargon, but this show needs Jimmy, and needed his eventual full babyface turn. Nucky worked as a tweener, i'm not so sure the show dynamic will work with him as a full blown heel.
If they wanted to knock somebody off, and have shock value, Nucky should have put the bullet in Margaret's head for signing the land over to the church.
