First off, a Warning: This review contains plot spoilers, if you have not seen The Daleks, read no further.
This is IT. The beginning of the most famous and recognisable, in Britian at least, villans ever to appear on the small screen.
The original designs of the monsters, the original Terry Nation Who story. And yet, although this is the first time that we see the Daleks it is very different to what they became.
In their debut the Daleks are not universe-conquering monsters out to chase and exterminate anything that they can see. They are people, they are a nation. Admittedly they are very suspicious and xenophobic, but only to the point of fear of what is not like them. They have clear and understandable motives.
The Thals were a warrior race, the Daleks were teachers and scientists, it doesn't take a genius to work out who probably started the neutronic war.
Having barely survived, the Daleks, horribly mutated, crawl into their city and prepare to let the universe get on with it. But it's not that simple. New Thals have apperared, a possible second attack.
The Daleks in this story are not clones, they are not, as Davros later put it "programmed". They do not listen to a black leader or a massive emperor, they debate and discuss until an accepted course of action is agreed on.
And even the neutron bomb isnt a weapon, it is the only way that the Daleks have discovered that they can survive. Far more subtle than the movie Daleks desire to "explode another neutron bomb and increase radiation to a point that not even tha Thals can survive".
And perhaps most disturbing, the last living Dalek, begging the Doctor to re-start the power grid as it dies.
The Daleks could have been a great society, with cultural eccentricities and class structures and people with personality. Instead they became a race of singular-minded robots.
It is still excellent, however, to watch this and see what could have been.
