Showtime have released a two-minute trailer for the seventh season of Dexter, which I've embedded above. It certainly looks promising, if only because the writers appear to have realised they can't toy with the audience any longer. For the first time in a very long time, we have a Dexter trailer demonstrating unequivocal progress of the show's underlying tension: Deb knows, or will soon realise, that her brother's the notorious Bay Harbour Butcher. I hope. There's still an outside chance this trailer is misleading us, but I'm willing to give them the benefit of the doubt.
Two more seasons are guaranteed right now, although there's recently been worrying rumours Showtime may push for a ninth season. That would be a colossal mistake. This show had a shelf life of five years, and they've pushed their luck to reach seven. I just hope season 7 and 8 will bring definite closure to the show (through salvation, death, or incarceration of Dexter Morgan), because witnessing The End is one of the key reasons I'm still watching. How about you?
