From IMDB:

A dangerously charming, intensely obsessive young man goes to extreme measures to insert himself into the lives of those he is transfixed by.

From Netflix you can stream two seasons of this somewhat creepy series. Each season contains 10 episodes each of which lasts about 45 minutes.

Joe Goldberg (played by Penn Badgley) at first seems just to be an obsessive stalker.  But harmless he is not. Joe spends 20 episodes talking silently to himself and rationalizing his behavior by somehow letting himself believe that everything he does is for love.  Along the way he manages to kill an awful lot of people in the name of love.

Is Joe mentally ill or just some kind of narcissist that chooses murder as a way to continue  his quest for love?  In any case he is not a serial killer in the accepted sense of the word.

Why watch Joe’s lethal progress?

•  All along we expect Joe to be killed or caught.  But cleverly unexpected events constantly occur to save Joe’s skin.
• Trendy dialog rules the day, especially in LA.
•  In face to face conversations, no matter what tight spot he is in, Joe always manages to manufacture a spin response.
• Good acting enhances a story that is never boring (although the very end seems to drag a bit).
•  Segments of Joe’s history as a sad, traumatized child are injected often to explain his current behavior.

Curiosity (as to how on earth this story ends) more than anything kept me hooked to these 20 episodes.
