ghoul or she blinded me with science

Though I do enjoy the added backstory and increased context with which vampire and zombie movies are portrayed, one trend that I find unsettling is the effort to demystify that undead with science. No longer is vampirism or zombification regarded as an unholy curse against the natural order of things but there is rather a cinematic discussion that's supported with all sorts of clinical trials, stating or at least suggesting, that it is a genetic aberration or a disease that bears treatment. I don't know if audiences are so opposed to the supernatural and would rather have rational explanations, but I do wonder if there's not a subtle message behind all these pharmaceutical monsters. I suppose that one cannot admit any superstition or anything inexplicable without inviting in God and the Church and everything that goes along with it. Reading about Vatican intrigues and minds that are swung just by the influence peddling of political cadres makes me wonder if there's not some conspiratorial design behind these sophisticated and scientific and Darwinian ghouls, keeping holier powers in check.
