We are renewed through five. It's all up to the fans, and if we keep getting this kind of response. https://t.co/54giw3S1PM

DEADLINE: So, are you planning on pulling the plug on Power at the end of a Season 6 if you get that too?
KEMP: This team at Starz, it’s really HBO 2.0, right? So they’re used to doing longer-term series. The Sopranos ran for a long time, Sex and the City ran for a long time. I conceived of this show as a five-season show, so that means that I certainly had a five season plan, and I could end it at the end of five.
But if they want more seasons, then our story structure is going to have to change to accommodate that, and so one of the things that we talked about was if the end of Season 3 is a jumping off point for two more seasons, or if the end of Season 3 is a jumping off point for three more seasons or more, we have to have a level of complicated storytelling ahead of us that will sustain that. We don’t want to run out of the idea, the basic idea, and so that’s all part of the motivation to have Ghost arrested.
