His favorite episode was raiden's and that one is full of mysticism, he mentioned he wants to create a build up to when a character uses his special move, like sub-zeros ice or scorpions spear for example. He said he made the rebirth short using his own cash so he couldn't afford special effects, that was the only reason he didn't give super powers to the characters. Plus hes aware of what the MK community wants, he reads the you-tube comments or boards and he knows what most people liked and didn't like. There was a full segment on the MK fighter weapons, mystical powers being considered weapons too.
So don't worry, im 100% the movie will have super powers and all that good Mk stuff, he just doesnt want it to look fake and cheesy.
