These are my personal opinions and may technically include a spoiler.
-graphics
I loved the cutscene graphics but the actual graphics for combat left me very disappointed. I personally preferred the MKX combat graphics. The hair especially bugged me.
- controls
Not really any complaints.
- characters/story
I started my enjoyment for the series in mkx and loved the characters and story. The ending of that game made me exited for this game, however I was very disappointed. They seemed to just toss away plot points that originally caused me to be hyped for this game. the antagonist I found bland and felt I had seen the same thing over and over again In other shows, games, and books. However I loved in the final fight if you lost there was a cutscene, that being said the ending felt like I had actually lost the game and I was left with more questions than answers. Not to mention the final fight was brutal and was infuriating (i was playing on easy as I mainly cared about the story). I was also bugged by the fact some characters seemed to not act like their selves and it bugged me to watch in cutscenes. I only had two characters I didn’t have issues with as I had not seen them outside of their revnent(?) selves.
All in all I just felt the game was a waste of time and money.
