the only show where a 'serial kill' is the protagonist 'hero'.. what year is it? how will dexters leo sister react to him being an even more twisted charlie bronson, for realz tho... (but only as fictional drama). In Real Life Dexter, during the series, was married to that skinny cat eyed sister of his Deb... it only lasted a short while. He had cancer bout, they split... wtf.
Most of these shows are difficult to jump into a few seasons later, after the char. dev. / the only show I cld easily miss a few episodes of, or even seasons, and still dig, was The Sopranos.
