For a while there, AMC was a network that could do no wrong when it came to original scripted series. First there was Mad Men. (I don't watch it, but people I respect love it.) Then came Breaking Bad (which just closed out a stellar fourth season and is still my favorite show on television). And then there was Rubicon, a slow-building but hypnotic show about the lives of intelligence analysts that crescendoed into one of the most gripping shows of 2010. I was devastated when it wasn't renewed for a second season.

But AMC is losing me with its new crop of programs. The Walking Dead started out okay, but this second season is testing my patience. For a show that has the word "Walking" in its title, there sure doesn't seem to be any sense of forward momentum. I don't think it's much of a spoiler to say that I'm sick to death of everybody being stuck at the damn farmhouse. It's more like The Walking-in-Circles Dead. Yes, I'm sure we're building to something, but is it too much to ask that the characters exhibit some personality in the meantime, or that the pacing doesn't flag like a sailing ship in the doldrums? The show only comes alive anymore when there are dead people on the screen, and that doesn't happen nearly enough. Frank Darabont's episodes last year had their problems, but he is nonetheless sorely missed. The zombie apocalypse should be more exciting than this.

And AMC's newest show, Hell on Wheels, isn't exactly bowling me over yet. The characters on this please-call-us-gritty western at least have the advantage of being far more colorful than any on The Walking Dead, but I haven't yet gotten the sense of much humanity beneath the surface of any of them. There's something a bit remote about the acting. I feel a great distance between myself and most of the characters. Colm Meaney is the exception, but his railroad baron is so over-the-top that I really can't buy him, especially in the way that he cheerfully explains his evil plans to anyone who will listen. If you're going to have such a loquacious villain, it helps to fill his mouth with great dialog, like Ian McShane's on Deadwood. But no one on Hell on Wheels, cast or crew, is operating at that level. Not that that would matter if they didn't seem to be cribbing everything down to the seams and themes from David Milch. This show literally looks like a low-rent traveling production of Deadwood. But maybe they'll find their way. (I really hope they give Common something more interesting to do than just look angry.)

Anyway, AMC used to get the automatic benefit of the doubt from me, but those are days gone bye.
