Kurt Sutter has posted his first blog entry about season four of Sons of Anarchy.

In it, he appears to address the main criticism from last season, which was still stronger than almost anything any other show on TV could offer, but which shifted the focus a bit away from the core characters.

The episode that start to air in September, however, feel "very potent," Sutter writes, adding:

"We're back in Charming, we're out of jail and we're making money. With that upswing, comes all the complications that success and power bring.  Season four is all about the club. The personalities, the history, the alliances, the conflicts -- the inside dynamics of an organized outlaw enterprise. Ego, greed, violence and fear reign supreme. I'm halfway through the cut of 401 and it's pretty fucking badass."

Among the storylines ahead, look for SAMCRO to face off against SAMTAZ. And, this is just a wild guess, but for some blood to be shed.
