Only a matter of time i suppose. I thought about doing something similar but my take would just basically be a padded out version of the Rebirth short - and maintaining that 'real world' style. And in a more chronological order.

I would say just call it Mortal Kombat - or maybe something like Mortal Kombat Prologue - since it's set before the meat of the MK storyline. I wouldn't keep the legacy tagline.

For now I'm waiting for the finale and any word on whether there'll be a 2nd season before I make any decisions.

in terms of what works, it depends on what sort of style you're going for really...

I'm not clear on this - are you keeping it in segments or one flowing piece?
