Well, you write what you watch. If you want to write Doctor Who, you've got to go back and watch it. Really watch it and study it.
Not saying I didn't enjoy Firefly, but if RTD wants to write in that style he should either work for Joss Whedon or George Lucas.
Steven Moffat makes an excellent writer for when he is given one serial per season, but a poor director because he does not understand what Doctor Who is. Years later, he might even admit that he never quite understood the core of Doctor Who and that he was unable to bring Doctor Who to what he wanted as director.
JNT took a number of years to get Doctor Who right. Unlike the old directors like Sydney Newman and Graham Williams who stayed for only a few years, JNT stayed for 9 and watched the show crumble apart in his hands. The difference between him and the old ones were that when Patrick Troughton was selected to be the second doctor, Sydney Newman did not want him to be the doctor but went along with it because his underlings might know better. Pertwee asked his first director how he should ask, and the director told him to be himself. Later the director asked Pertwee what he wanted and Pertwee responded that all he wanted was 'two moments of charm.' The directors were there just to see things go smoothly, it was the Doctor who was the star of the show and who had a huge level of power and control (though the second Doctor had to sit on strikes with his companions to get time off from filming).
For JNT, he did not understand this until the sixth's Doctor's second season, but by that point it was too late.
Turner's attempts to bring the audience in with cleavage (Peri) was not going to fly for poor/strange writing. Though, if he were not dead, and he returned to being director, he would probably be a better pick than RTD and Moffat through sheer experience alone.
We all, however, would prefer someone who was faithful to the old series. Someone who was not a novelist from the canceled period, or a visionary for new who. Although the seventh Doctor showed some potential and things were beginning to get a bit interesting, the series had already divulged so far. I can't complain too much about Lungbarrow which followed with the Seventh Doctor's arc, it was too different from the essence of Who. I'm afraid that JNT could not restore the series to the place where he left it no matter how many years he would be given.
