If history holds, The Walking Dead will once again set record ratings for AMC Networks (AMCX -0.60%) when Season 4 makes its debut this October.

How can I be sure? Because, as is his style in the comics, Walking Dead creator Robert Kirkman has a way of making sure the next story is more gruesome, more awful, and more terrifying than the last. Season 4 will be another adrenaline-booster.

"Things are definitely going to be WAY crazier. It's an escalation. I mean, the world is getting worse, the people are getting more ragged, there's more terrible things happening," Kirkman said in a Friday afternoon panel discussion at San Diego Comic-Con. "Things are going to keep progressing, if you can believe that."

Anyone who doesn't take Kirkman at his his word must not watch the show or read the comics that started it all. Still skeptical? Watch the trailer, if you can stomach the sight of zombies and kill shots:

In many ways, The Walking Dead is a reminder of the sorts of fare that established AMC in the first place. Classic and new horror films still have a home on the network's "Fear Friday." The difference is that TWD isn't so much a horror show as it is a human story set in horrific conditions.

For example, actor David Morrissey plays a character called "The Governor" who justifies brutality in the name of survival in a world gone mad. He'll be back to torment the main cast in Season 4.

"He's still out there," Kirkman said at Comic-Con. "But how he returns, when he returns, and what he's doing when he returns is going to be a pretty big mystery this season."

Among rival networks, only HBO and Showtime have shown a consistent willingness to push boundaries as much as AMC has with The Walking Dead. Count Netflix (NFLX -3.92%) among the rare exceptions. Hemlock Grove with its werewolves and Orange Is the New Black with its dark depiction of prison life both take joy in tormenting the squeamish.

But these are the exceptions, and that means AMC is likely to keep drawing in millions of viewers who enjoy its darker tales. Are you among them? Leave a comment to let us know what you think of the show and AMC stock.
