The problem with the season finale is that, really, nothing happened. It was such an underwhelming and anticlimactic end it's absurd. They built to this big showdown with the Governor, and then...well, nothing. They scared his people off with two guns, basically, and then he shot his own people and disappeared. Such BS.
And then Rick decides to take in the people of Woodbury. I'm fine with that. But the fact that he brought them all back to that dirty prison, which has seen several breaches in security so it's not that much more fortified than the town, is ridiculously illogical. Woodbury had running water, actual homes, it was well fortified, had supplies, etc. Kirkman said in an interview, in a total cop out answer, "they went to the prison because the Governor is still out there." What utter BS. He's out there, but he's unhinged and without an army. He has TWO OTHER GUYS, and that's it. Plus, those two seem awfully skeptical of him now, and they are all running dangerously low on ammo. So why on earth would Rick and the now dozens of people under his care give a if the Governor is still around? It's literally 3 versus probably 30 or 40.
