The fantastical elements needs to be EMBRACED, not shoved under the rug. All you need to do is poll people on their favorite MK characters to know that. If you ask someone who their favorite Mortal Kombat character is, 9 times out of 10 they will spout off someone like Scorpion or Sub-Zero who has mystical powers. I've never heard anyone carry on about how much they love Liu Kang, Jax, or Kung Lao. It is the violence AND the fantasy elements that people love about the franchise...........not how "realistic" it is.
I'm glad that WB is letting him go full-on for an R rating. That said, I'll be shocked if he can squeak by without including the fantasy aspects of the franchise. I really can't see Warner Bros. letting that fly. All questioning aside, I'd love to see Michael Jai White (and Scott Adkins) propelled to stardom through something like this.
