3 Headlong Into Mediocritydeanlowdon | 05/07/2012 | See all deanlowdon's reviews (468)Top 100 Reviewer Top 100 DVD Reviewer Guest starring Edward James Olmos and Colin Hanks Dexters sixth season finds Dexter Morgan on the hunt for a pair of serial killers, known as the Doomsday Killers, who are seemingly being inspired by stories from the Christian Bible. In fact these religious overtones are very much the theme of a season which, while not quite the train wreck some fans would want you to believe, undeniably continues the shows rapid decline into mediocrity.Part of the problem lies with the overuse of these religious overtones but the largest issue is that while in its earlier seasons the writers always strived to retain some sense of plausibility making for tense viewing as Dexter Morgan kept his dark urges from his closest friends and family much of this has been eroded with each passing season. In its place cheap plot devices, that often find Dexter quickly discovering and dispatching yet another criminal that the LAPD seem to have missed or on some occasions killing people on the spur of the moment, yet still getting away with it, are becoming increasingly common. There are plenty of other examples of lazy writing, including characters constantly talking out loud to themselves just to explain things to the audience, that simply where not present when the show first hit the air.A once great show is now really no better than the majority of other drama series on air and I have come to expect more from Dexter. If it is ever to return to being essential television once again its seventh season needs to return its sense of believability (please stop putting him in situations in which he escapes at the last minute!) and recapture what first attracted its viewers. This season's final scene certainly hinted that the show may be willing to shake things up a little so I still hold out hope.
