Matt Smith on Series 5 & 6

Matt Smith spoke recently at Wizard World Comic Con about his first two seasons as the Doctor

For me the best storytelling was in Series 5. It had great adventure and great clarity and I loved that whole idea about the Pandorica and the Big Bang. It was the one I connected with most. I think in terms of revelations River being Amy’s daughter was a bit "what the hell?!" Looking back I think some of my best work was in my first series because I was actually taking real risks and that was a real moment.
