Give it up for multiple Emmy nominee Michael C. Hall, because, without his consistently rich performance as the serial-killing title character on Showtime's long-running Dexter, we'd have abandoned this ship two seasons ago. Far too concerned with its distracting side characters (fingers crossed for a "Batista es muerte" moment this year) and stretching plausibility way beyond its acceptable limits, the most recent Dexter seasons rank as some of the most infuriating television imaginable, so it was a pleasant, applause-worthy surprise when last year's sixth season finale finally blessed fans with the inevitable: hot cop Debra Morgan (Jennifer Carpenter) discovering her brother's homicidal secret.
On the other hand, it's unavoidable that Dexter will further explore the laughable subplot about Deb's romantic attraction to Dexter. One can only pray that, as his after-hours practice becomes more widely known amongst his peers, Dexter's "dark passenger" will fly off the rails and go full psycho. Otherwise, not even Hall's fine acting will keep largely fed-up viewers on board.
