First episode inherited a lot of the old rubbish, like Murray Gold and some dumb hacking, also that "hip" BBC1 hyperactivity. On the other hand, Moffat is blatantly superior with dialogue and his pacing makes the RTD signature set-piece look obsolete as well as crude.
On its own I would say the episode is only a minor improvement; it's more evolution than revolution (e.g. the console room and the titles sequence), but it takes a lot to change a show's genetic code. Robot, The Twin Dilemma, and Time and the Rani were all era-openers that looked more like their predecessors' than something new.
I may be deluding myself into thinking that Moffat has a radically different vision for its future... but it would be hard for me to reconcile Moffat, who I think is the smartest writer in Television, with one of its most flawed shows forever.
