I don't know yet. I'd have to actually see an episode.
So... as an update, not only did a kind and wonderful friend give me the 4th season (new episodes) as a Christmas gift, but the
same kind friend also gave me the Hartnell "The Beginning" set of the earliest episodes, as well as three key Tom Baker stories. (Robot, Genesis of the Daleks, and the Hand of Fear)
The new guy seems a bit young to me, but I try to keep an open mind. (I'd been vaguely hoping for a sort of steampunk look for the next one.)
