Much as I religiously sit down every Saturday to watch it I do find myself enjoying the old Pertwee/TBaker ones much more than the current reboot.
Maybe it's part nostalgia but in the absence of budget for special effects plot and characterisation played a big part in each episode. Now I feel the "plot" mainly involves the current incumbent girning to camera whilst flapping his magic wand in all directions at once. Characterisation should not be replaced by caricature.
Gatis scripts aside, Moffat's seem to be all spectical and little substance. Good for the occasional extravaganza but it's like overdosing on chocolate meringue. One bite and it substantively collapses.
On the plus side, the eye-candy has certainly improved :)
