The correct answer is Kronika. Wish I could say this on reddit without getting downvoted to oblivion, but I'll say it here... Until we get a downvote button...
MK9 Story was a 10/10, I think we can all agree on this. It was a rollercoaster, no one knew what would happen on their first play, references and fanservice throughout, fantastic flow, you cared about almost everyone, fantastic cliffhanger ending. Great for long time fans and newcomers alike.
MKX I would call an 8/10. Solid. Chapter 1 is everything you wanted coming out of MK9, but it was sort of downhill from there. Not to say it was bad, it's fun to watch from start to finish. I think the writing was fine, but the direction they chose to go in was weaker. By the end, we had plenty of interesting lasting impacts. We saw Johnny all but replace Liu Kang as earthrealm's protector, Scorp and Sub Zero patched things up in a believable way. Most importantly, Raiden's frustration finally got the best of him, character development with roots in MK9. And the Revenants had supposedly gained a semblance of free will, so we were set to see the culmination of Liu Kang's anger at Raiden from MK9, something that has never been properly dealt with.
MK11 is a 1/10, from start to finish, and it is jarring. The writing is clunky and hamfisted all around. We're immediately thrust into more conflict, with an apparent time-skip in between. No one's in character. Most importantly, they never follow the rules of "show don't tell." They tell us Kronika is important, but we never see why. We're told Raiden is an ass, we never see this. The list goes on. Worst of all, they undo threads we've been waiting years to see wrapped up, namely with Dark Raiden and Liu Kang. Hard to characterize Revenants when their motives boil down to "evil because undead voodoo magic." I say these things out of love and disappointment for MK's story.
