Irish makeup artist Julian Checkley may or may not be able to act - though he can most definitely gesture threateningly - but he wears that Sith Lord outfit like a nightmare come to life. Also, he built the entire get-up from scratch over six weeks. Yeah, the character is basically Vader without most of the helmet and sporting yellow and red "Sith eyes," and his name sounds awfully like some dude named "Gus" decided to call himself "Darth Maul" and screwed it up, but hey, Julian didn't create the guy - he just recreated him spectacularly.
Now witness the time-lapse of Julian transforming from civilian duds into a fully armed and operational battle Sith. It is your density.
