“Dexter”, the Showtime series planned to air tonight on CBS, had to undergo some changes in order to fit with the network’s requests.

Some of the curse words had to be replaced and the violence scenes were cut.

Nina Tassler, the president of CBS Entertainment, tossed away the concerns that were hovering around the series saying that it has been edited and that is scheduled to go at 10 p.m., a time when most of the children are in bed.

“Dexter” will air Sundays at 10 p.m. beginning Feb. 17, over consecutive weeks. This is the first time a full season of a premium cable drama series transitions to broadcast TV, CBS said. It will run the first 12 episodes of the first season.

The show had its first premiere on premium cable network Showtime on October 1, 2006 and is currently preparing for its third season.

The series is set and produced in Miami, having at its center Dexter Morgan, a serial killer, who works as a blood pattern analyst for the Miami Metro Police Department.

He was orphaned at three and was adopted by a Miami police officer, Harry Morgan, who saw that Dexter (Michael C. Hall, “Six Feet Under”) had sociopathic tendencies but never got him professional help. Instead he taught the boy to use his passion for killing in order to murder people, who “deserve it,” who slipped the justice system.

Even so, Dexter has taught from Dexter to fake normality and keep up with the appearance. He is liked by most of his colleagues, his girlfriend, Rita, and her children.

The first season, scheduled to air tonight on CBS, evolves around a serial killer, “The Ice Truck Killer” who is communicating with Dexter using his crime sets.

Showtime’s president of entertainment, Robert Greenblatt, said that the revising of the 12 episodes started in January and that most of the modifications consist in language and some cuts of specific scenes.

Actors on “Dexter” recorded alternate dialogue in order to substitute the bad language, a practice used by cable televisions producers.

Greenblatt said that the series rely less on shock value and more on hints of violence.

He said: “People who haven’t seen it think it’s like the ‘Saw’ movies or some other horror films. We suggest violence — he picks up a knife or turns on a power drill — but then we cut away,” the New York Time reports.

“The things that are unconventional about it are still 100% there,” he added.
