Does it really matter who takes over? If it doesn’t work out then-ok. Move on. All we know at the mo is-new Doc,new producer, probably new Tardis makeover. A lot to look forward to. I’m no fan of “political correctness” or box ticking, but its clearly a brave new direction.
One thing I would like is the absence of any kind of romance for the Doctor(whether its a he or she). The Doctor in my mind should be sexless and above such behaviour-the Rose/Doctor thing irritated me a lot. Really looking forward to JW
