Oh, my little darkly dreaming Dexter — my, how you have grown since first coming into our lives in 2006. You've gone from being a minor cult item about a serial killer who targets serial killers to a record-breaking hit show with several awards and nominations under your belt. You even somehow managed to survive an entire season featuring Julia Stiles as your recurring guest star — something that very few series would be able to endure. Now, here we are with your sixth season at our sides, and I am forced to say that I am not entirely sure what to make of the direction you are clearly taking.
Dexter: The Sixth Season finds our antihero at a moral crossroads in life. Sure, he's a pretty soulless individual, but his newfound single father routine has taken him to what one might call a higher level. The season opens with Dexter looking to enroll his son into a Catholic preschool, wherein a nun asks him about his religious beliefs. From there, Dex begins to look into the more spiritual side of existence — something he doesn't actually believe in, but something that warrants further studying once a pair of devout Christian nutjobs (Edward James Olmos and Colin Hanks) start to panic the entire city with several grisly murders they believe will bring about the end of the world.
Otherwise, it's business as usual for the crew of the Miami Metro Police Department. Lab geek/perv Vince Masuka (C.S. Lee) is on the lookout for an intern, to wit he welcomes aboard two completely different candidates. Sgt. Batista (David Zayas) finds it hard to focus on being overprotective to his younger sister (Aimee Garcia) — whom we have never met before, and who also serves as Dexter's nanny — since he is busy butting heads with his partner, Det. Quinn (Desmond Harrington), who turns into a raging alcoholic when his marriage proposal to Dexter's sister, Debra (Jennifer Carpenter) goes awry.
