What adds so much depth is the flashback scenes to Dexter's childhood and how Dad teaches him; all the tricks to acting normal, all the ways to curb his bloodlust (like taking him hunting), and how important it is to only attack evil people. James Remar plays his dad, Harry Morgan, and does it very well. We see the moment when dad realizes the kind of person Dexter is while the boy is very young, and he takes it in stride and begins teaching him right away. There never seems to be a moment when dad questions the morality of what he is doing, he merely proceeds with his modeling of Dexter as if it was the most natural thing for a parent to do. Especially a parent who was a cop. The most recent episode gives us the best clue to his motives where he tells the teenage Dexter that it's no fun to teach him how to kill people without getting caught but it's the only way he can think of to keep Dexter out of the electric chair.
In the first episode Sgt. Doakes (Erik King) tells Dexter that he gives him the creeps. Dexter then muses how odd it is that in a building full of cops Doakes is the only one who gets the creeps from him. And Dexter's sister is a cop as well and Dexter helps her out with tips (who knows a serial killer better than him) on the Ice Truck killer who is cutting up girls in Miami. But there is an added twist with the Ice Truck killer as well - he knows who Dexter is and leaves hints for him. "My friend wants me to come out and play and I want to," narrates Dexter.
But when the Ice Truck killer turns the tables on Dexter and has the cops and his own crime lab investigate one of his murders (circumstances forced him to rush, no other murders are known about) Dexter starts to panic. Until he gets the idea of turning the tables back again by giving the police another suspect by planting the very evidence he is supposed to be examining. His sister Debra (very well played by Jennifer Carpenter) works up a profile of the killer which matches Dexter exactly, but of course she would never suspect him so it doesn't occur to her. When Dexter plants his evidence it blows her profile out of the water and causes friction between the siblings. But Dexter knows she will get over it.
I would call "Dexter" the best new show of the season. Bizarre, creepy and likable, it wins points simply for uniqueness, the fact that it's well done and well acted is a wonderful bonus. There are many shows I like this season but only Dexter, Studio 60 and Battlestar Galactica make my "must see" list.
Giving times for it can be difficult for a cable show as they change it between time zones, it premiers each Sunday night, in SoCal it plays at 7 & 8pm plus 10 & 11pm and is repeated several times during the week.
