The Dark Side of The Force
Some Star Wars fans are into the Jedi (or Light Side of The Force). Me, I'm more of a Sith guy myself!
I have a particular fondness for 80s hair metal which is what I grew up listening to.
Cheesy Horror Flicks
That, of course, includes A Nightmare On Elm Street, Friday the 13th, Chucky and so-called "slasher" flicks in general.
Dark (or Politically Incorrect) Humor
To me, pretty much nothing is "sacred" and, if it is, it won't be when I get done with it!
Dark Haired Women
I feel this one is pretty self-explanatory. (Pretty-get it?)
Many-or most-people like to root for the good guy in films & whatnot but I feel what makes a show good is a really villainous bad guy.
And pretty much anything macabre.
By "macabre" I don't mean that I'm a practicing occultist or witch or anything like that but that I'm usually "attracted" to stuff others might find eerie and, of course, dark.
