One of the things I like about pulp is that unabashed use of popular tropes, tropes which become archetypes and seem to stand for something eternal and inescapable. Episode one of The invisibles is full of them.
I remember seeing as a child the bit in planet of the apes where charlton Heston finds his friend in the cafe captured by apes and his friend is just... not there. His mind has been zapped. He doesn't recognise him, he can't talk. He's alive but he's been erased. Very horrifying, very disturbing for me to see that. A terrible fate.
