Watched this last night. EXCELLENT!!
I'm not a huge zombie flick fan. I've seen a ton of zombie films, but usually I'm not that excited about any of them. The spate of films that have sprung up the last five years or so are boring, and overdone if you ask me.
This film (and yes, it was more like a film than a television show) really impressed me. It was excellent in it's detail (the insect noises in the heat of summer, and the filth and bottle flies everywhere around the dead are just a couple of examples). Frank Darabount spared no detail or expense for the first episode. In fact the only thing I fear is that because he is only personally directing the first episode, it might not live up to it's debut the rest of the season. Either way. I'll be tuning in to see for sure.
I haven't read the comic, but the show was really awesome.
