MINOR SPOILERS FOLLOW:Breaking Bad creator Vince Gilligan hinted a while back that he envisioned the story of chemistry teacher turned drug dealer Walter White (Bryan Cranston) ending after a mere five seasons, insisting that the narrative will have run its course by then, and that the intended story will reach its climax. Refreshing, to say the least, in an industry that thrives on running TV shows into the ground until there's nothing left of them (but syndication can began, don't you know?). Of the show, Gilligan said, "This was never intended to be an open-ended show. As creators of the show, we have to see it through to the end, to finish what we started." He implicated that the show will end its run during the next season (season 4 is currently airing). It's clear to see where Gilligan is coming from: Walter White began his journey with good intentions, and as a character, he was definitely somebody with whom audiences could sympathise with and root for. Over three seasons, audiences watched in horror as this geeky, good-hearted father and husband became a man they could no longer recognise. Consumed by his plight, he emerged as a liar, a murderer, and now, an antagonist to those around him. Slowly, the Walter White who worked a second job at a carwash and stood up to nobody, has transformed into a villain. It's a highly unique take on the television format, as characters - especially main characters - don't tend to arc in such an extreme fashion, and rarely ever shift from good guy to bad guy. But Breaking Bad has always been unpredictable (and utterly volatile). Now, as the true tracks of AMC's greatest show ease into focus - that this was not a show about a man who would finish with his head held high, after all, but a show about a man who becomes an unbelievably destructive villain - there's hard proof that this television outing is truly something special, and something we've never quite seen before.
