It was a proof-of-concept short created to try and get funding for a new movie.
Meh.
Seriously. I was a huge Mortal Kombat fan in the 90s, but the series is dead. It was all sizzle and no steak even in it's prime. Why revisit it now? It hasn't been culturally relevant in about 15 years, and the mythology it's based on is stupid anyway.
Might as well make a Frogger movie or something. Or a gritty reboot of Q-Bert staring Vin Deisel.
