(TV) Dangerous Exploits follows a young man's journey from a womanizer to a brilliant sociopathic manipulator, starting with his graduate studies of psychology at Arizona State University.

Ok, your protagonist is obvious, the young man, but what is his goal(s) that he is trying to accomplish? Is it to become a "brilliant sociopathic manipulator"?
And what/who is the antagonist that he must overcome? What is the conflict in your story?

hmm very good point, that is definitely something I need to think hard about for this logline; why the viewer would be on his side

>>but you?re on his side.

Are we? Why should we be? Give us a good reason. Which, I admit is difficult to do given the constraints of a logline. What is there about your sociopath that will engage our interest, perchance sympathy, even as we don't like how he operates?

awesome that you made the Dexter connection - he is well mannered and very likable, as well as with a flashbacks that explain what made him the way he is. Like Dexter or BrBa, the protagonist may not be a good person, but you're on his side. First few seasons are purely his journey with self, figuring out how he is to live his life, developing his skills and how he plans to use them. I was thinking politics for later, but having just moved to LA, might be easier to write more what I know.

Journey through what occupation? (Politics or show business are the 2 natural fits-- the streets of Washington DC and Hollywood are littered with men who fit the description. He'd fit right in.)

As defined, he doesn't seem to me to come off as an inherently sympathetic character. So what's to keep the audience tuned from one week to another? Does he have any redeeming characteristics? (Like Dexter in the Showtime series who is a serial killer -- but sublimates and only kill the bad guys.)
