Firstly I wasn't going to open this thread until I'd watched episode 3, which I did last night. It was all about the Doctor standing on a landmine. If Anita Dobson was the face of the 'Ambulance' then she has really aged.Episode one i found weird with the babies. Episode 2 I loved the Maestro and helped show there are some very powerful beings in creation and the Doctor isn't one of them. Episode 3 showed how the doctor just walks into problems and has the brain to fix things but needs a companion to help him. Episode 4 shows again how the Doctor just walks into problems, but this time it was the companion who has to fix things. Everything so far has shown that the Doctor is not this all conquering hero he has been. He is succeeding by the skin of his teeth and needing help to do it.
Anyway, I digress. Yes I agree with you. Originally the Doctor was not much more powerful than a normal human, just a bit brighter. If you locked the William Hartnell or Patrick Troughton doctors in your shed first thing in the morning, they'd still be there when you came home in the evening. Later doctors, with more and more gadgets and powers would escape in an instant. In recent years the Doctor has become this phenomenally intelligent, all-knowing, semi-immortal being with god-like powers, so I'm glad they've scaled him back a bit.
Talking of William Hartnell, going back to episode 2 (Maestro), why didn't he notice the death of music? One of the reasons Susan didn't want to leave the 20th century was because she loved Sixties pop.
