I wanted so much to love Dexter.
Season 1 was awesome.
But when they tried to 'humanize' him they fucked up the show pretty bad. As if people couldn't cope with the main character being bad.
Newsflash: they can.
Hannibal, Games Of Thrones & Breaking Bad all feature pretty 'disturbed' (and highly entertaining) main characters and that is why we love'em.
