Adam Adamant Lives!

Having just turned off half way through the first episode, I'm afraid in my opinion Adam Adamant Lives was badly acted and had an appalling script. Adamant is meant to be an Edwardian gent, but has never come across underground trains, escalators, cars, electric lights or telephones. Of course this is a fantasy but I do expect a certain amount of internal consistency. Why not have Adamant as a Victorian detective (say having been frozen for 100 years instead of 60)? I don't feel I need to make allowances for the budget or the production values that British TV had at the time - it costs nothing to have a decent standard of script writing or acting.
