Great mid season finale!
So...
-The plan for the Gov and his group was to make the prison their new home yet they're blowing up the damn building into pieces?

@ Daryl using the zombie as a shield when the scene right after that was Bob talking about exit wounds
LOLWTF
They struggled with the Governor's character. In the comic he was a lunatic and everything he did was crazy, so behavior like this would have been par for the course. The character was scary because he was unpredictable, but it made you question why anyone, let alone a town full of people and ex military would follow him.
With the TV show they made the governor more strategic and intelligent, but what that ended up doing was making events like the "knock down the fences, kill them all [by shooting a tank at the walls]" not make any sense.
I get that the point is he cared more about killing Rick et al more than he did protecting his people, but after spending the last two episodes and the first half of this one emphasizing how he's slightly changed and has different priorities some of his actions made no sense.
His character was poorly written and inconsistent.
