Yes there are realistic elements here, but most negative comments mentioned are purely assumption. There wasn't anything said about no super natural elements being added at all, nor is Shang Tsung said to be some Mob Boss. Ever considered that an Earth Realm cover? Of course you haven't. The additions of realistic elements makes the concept so much more intense, more relatable, and likely the fantasy elements is what contributing to making the former movies so lame.
This is an amazing concept (and considering it's less than 10 minutes, there isn't much too assume here), that makes Mortal Kombat in any film form return to it's gory, intense roots. Whatever they need to do to actually make a crazy, violent MK, is fine by me. I cannot wait for the Web Series to come out, then when that hits it off, somebody get's the balls to actually make a kick ass movie from this (or maybe a Starz or HBO series similar to Sparticus, minus the lame Roman stuff).
OH and by the way for you slow people, I guess you didn't notice that "Scorpion" had no eyes in this? Most likely not.
