The resurrection of popular shows has its fair share of potential problems, not least a concern that fan favourites will be bled dry. Did Ricky Gervais get it right with The Office and Extras when he decided to leave audiences wanting more? Arrested Developments resurrection had mixed reviews and was even seen by one critic at the Wall Street Journal as a shaky imitation of itself. With audiences divided, it still looks likely that Arrested Development will return for a fifth season and possibly even a feature film, but will its legacy be damaged as a result? While Family Guy and Doctor Whos resurrection have been a bone-fide success, Futuramas resurrection on Comedy Central led to falling viewing figures and a cancellation after two original seasons. Futurama is not alone in its short-lived resurrection, Primeval and Jericho also met with a similar fate. Will the revival of axed programmes see us milking even more future classics to death? And will fan demands and enticing offers from on-demand services combine to create too much temptation for show creators who should know when its time to quit?
