I did find the article’s point - that having a comically evil villain can sometimes work out really well as a narrative device - to be relevant. The example that the author points out - that some people are just plain evil and their malice is beyond comprehension - is exhibited really well by the Joker. A few other memorable examples that come to mind where such villainy plays off its absurdity to make a larger point are Gary Oldman in
Leon the Professional and Tilda Swinton’s various villains in Joon-ho’s films.
But far too often the one dimensionality is used as a lazy writing device and serves as a showcase for an amateurish script.
