Steven Moffats tenure as showrunner of Doctor Who has been something of a rollercoaster. His writing during this period has brought fans the highs of The Day of the Doctor and Listen along with the lows of The Wedding of River Song and In the Forest of the Night (yes, he didn't actually write that last one, but how he allowed it to get produced the world will never know!). It makes Love & Monsters look like The Caves of Androzani. The recent announcement that he is going to stay on for Series 10 will undoubtedly have fans up in arms. After all, Russell T Davies had 4 seasons and a couple of specials and Moffat is already exceeding this count by staying on for Series 9 (his fifth season at the helm). Is it not the Grand Moffs time to bid adieu to Who? Fear not, Whovians! Moffat's staying on through Series 10 is not necessarily a bad thing. Love him or hate him, Moffat has done a lot of good for the show. If Russell T Davies' greatest contribution was reviving Doctor Who for a modern audience, then Moffat's greatest contribution has been turning it into even more of a global phenomenon and helping to bring the show into the 21st century. With his future assured, here are 10 reasons why Steven Moffat staying for Series 10 is actually a good thing.
