The New Dr Who is being done with modern and well done speciall effects.
The older Dr. Who was prone to wrap a guy in tinfoil and bubble wrap to play an alien.
The concept was always the thing , Dr. Who has the ability to visit all places and all times so the experiments of thought were unlimited.
Star Treck ,B5, Star Wars and etc have a very strong special effects standard , which I really like .
But Dr. Who seems to have lost something in the gaining of a special effects budget.
The old Dr.s fought their limitations in costume and spetacular effects by being imaginitive and convinceing in dialog and concept.
