I am not a big fan of TV - for a number of reasons - time constraints, commercials, and the fact that many of them are not entertaining enough for me to suspend all sense of reality.  BUT over the holidays I was convinced to watch Dexter.  Started with Episode 1 Season 1 and went right through the entire 2 seasons within a few days !  This is a series where the star is a serial killer - he kills bad people - but only if they deserve it.  He has his own code which requires that he prove to himself beyond a doubt that the person deserves to die.  And I like him - he's a very likable person -  and I was rooting for him during each episode.  When his identity was almost discovered I was upset, anxious and actually hopling that he would be safe.
