it's an uncomfortable truth that sometimes people can be monsters unworthy of humanity.
fruit of the tree of the knowledge of good and evil. its a mythological story about the emergence of consciousness into humanity. came with it was the discovery of time and "the future", then the realization of vulnerability and the need to protect oneself, then the extrapolation that "if I can be hurt in xyz ways, I can make others hurt in those same ways". consciousness begot the potential for both great good and great evil.
people manifesting their evilness has been a problem since the very beginning. I think it helps to know that it's not a new, modern age problem. but we should still try our best to minimize it much as we can.
The Woman in Black with Daniel Radcliffe is absolutely terrifying. not jump scarey, just intense dread and horror as some of the scenes linger on.
the sequel was alright but couldn't quite match the intensity
