Seeing it recently, it seems pretty tame. But at the cinema on release, it was feckin terrifying. It really was.
I guess time and movies getting more gory and shocking have dulled it's edge.
Like many, Daleks scared me on TV. Their total lack of compassion and single mindedness was truly frightening to me. I had nightmares about them literally coming down our street.
Also for me personally, was my mum's old Victorian doll on top of her wardrobe. Freaky after seeing that TV show with the ventriloquist's dummy that came to life... I always expected it's head to turn and follow me as I walked past it.
The other was the dead coming back to life. Way before all the modern zombie films and books. The image of their lifeless rotting arms, breaking through the earth of their graves was the generator of many other nightmares for me.
I reckon that fear came from seeing my uncle and aunt 'laid out' in their parlour. (Catholic family, it was the norm to see such, even for kids)
