An "atmospheric character drama" without any atmosphere, and precious little drama
The subliminal mind has many dark, unhappy corners, after all. Imagine something loosening itself from one of those corners. Let's call it a - a germ. And let's say conditions prove right for that germ to develop - to grow, like a child in the womb. What would this little stranger grow into? A sort of shadow-self, perhaps: a Caliban, a Mr Hyde. A creature motivated by all the nasty impulses and hungers the conscious mind had hoped to keep hidden away: things like envy and malice and frustration.
