Yea, I'm not a fan of Negen. He's very exaggerated. I felt the same way about him in the comics too. I think they chose the wrong dude to portray him. I just don't think he's a very good actor. I was hoping they were going to take some liberties with him, and tweek the character from comics to t.v. like they did The Governor. So far all they tweeked was the amount of obscenities, for obvious reasons of course. Oh, and they picked a skinny old guy to play him instead of a dude that looks like a linebacker. He was tolerable at times in the books, and worked for the storyline I suppose. But, on the show his mannerisms, body language and everything just bugs me. Thankfully he's not enough to ruin the show, or hinder the storyline.
Maybe that's the point. He's supposed to annoy the shit out of me. I just don't find him convincing, or intimidating. I have a hard time suspending disbelief that this tall skinny prick could organize a bunch of hard asses to follow him. And if there's one thing I value in a show about zombies, its BELIEVABILITY!
I didn't care much for Ezekiel in the comics either. Oddly I like they way he's portrayed on the Show so far. He's alright.
I honestly hope they defeat Negen this season, and they don't drag the storyline out. The next storyline from the comic is much better. What I've read of it anyway.
