I've watched this twelve times already today. I adore it and could give it no less than five stars in good conscience. I particularly enjoy the split-second of sickening detail on that lead zombie (he's great, by the way) and the stark contrast in the words of his next line and the look on his face. He don't give a ****? He sure looks like he does.
All in all, it's a beautiful piece. My only issue is that no matter how many times I click the easter egg it won't cooperate, but honestly, it's perfect without that. The epilogue was neat and I can't wait for part III.
