Say hello to Negan. Well, that's the actor Jeffrey Dean Morgan in action, but you get the idea. His character is all set to become the show's greatest villain to date - not that there's a lot of competition aside from The Governor anyway. You won't find any specific plot spoilers here, but know this: Negan is a bad, bad, bad man. He's boisterous, larger than life, cunning, malicious, and utterly brutal when it comes to killing. I can't help but feel like the show is stagnating slightly, and that makes Negan an even more important figure. He could genuinely revitalise The Walking Dead itself, and if his comic book story does play out the same way on screen, the internet will explode.
