I am actually kind of indifferent towards Rick. He REALLY pissed me off with his "this is no longer a democracy" comment though. Him and I would have problems if I was part of that group and he said that.
I think they should stick to the original story line
Seriously. I think they should just play it close to the vest and stay true to the graphic novels. Not too many adaptations do stay true but the series can be even better than it is now. Its simple...do not stray too far off the path painted for you...
As already said, he is the main character, especially after the death of Shane, so he won't be going anywhere.
In terms of acting skills, Andrew Lincoln is not so good.
He tries to play an Alpha male but it's clear he isn't one in real life.
I just laugh when he tries to hard to speak in a deep voice. It reminds me a bit of Christian Bale when he plays Batman.
Shane, played by Jon Bernthal, was by far the best actor. The only reason we all hated him so much was because he played his part so well.
He had a natural leader feel about him, shame the writers made him the b*****d.
I wish they would have swapped roles.
