Why He Should: As far as experience with Doctor Whogoes, Roberts is second only to Gatiss on this list. He has consistently churned out quality episodes, and shows a certain deftness when it comes to balancing the dramatic and comedic aspects of the show. Additionally, Roberts has been a consistent writing partner for both Davies and Moffat, and who didnt love the pairing of James Corden and Matt Smith in Series 5's The Lodger and Series 6's Closing Time? Why He Shouldnt: For as much fun as Roberts writing is, he has a tendency to cop out when it comes to endings. Closing Time came way too close to the clichéd love conquers all ending, and then there was Danny Pinks ridiculous flip at the end of The Caretaker. Much like Gatiss pulpy style, Roberts writing probably wouldnt translate too well to a showrunning role.
