In an interview with Vibe, Ellis explained that the show does not have any boundaries.
"It's [successful] because it's edgy and sexy," he said. "Everything else is kind of chained and p*ssy. With True Blood, you don't know what to expect. You don't know how wild it's going to get."
However, Ellis added that the show is popular because the stars are talented.
"It's like the Jerry Springer of TV shows but at the same time you got legitimate actors," he said. "Everybody on there is a legitimate actor who's trying to get to the place that the writers are trying to send us to.
"I don't think there's a show as edgy, innovative and quite frankly, they're shot well. Each episode looks like a movie, so I just think True Blood has more edge and it has more spontaneous stuff that goes on."
True Blood continues on Sundays at 9pm on HBO.
