I just played the story mode again, this time with my bf, and I didn't spoil anything for him. Seeing his honest reaction to the story was very interesting, but it didn't surprise me at all. He went from thinking everything was awesome to just rolling his eyes every ten seconds after Sindel's chapter. I could almost feel him physically cringe every time the word "timeline" was said. But like me, he felt that the story mode was overall way more enjoyable than MKX/MK11. I found it particularly funny how he just gave me the most massive eye roll when they talked a bit about Kronika and her motivations in the last game. I've been told to "touch grass" a couple of times when I complained about the way Kronika was written in MK11, but I've yet to find a single person that I know irl that liked that story. He also felt that the ending kinda just... happened out of nowhere and was pretty anticlimactic.
I just can't get over how terribly shitty Sub-Zero was in this game. That's a point where Keeper of Time Liu really dropped the ball, it seems. Every other villain was directly or indirectly influenced by Titan Shang. Bi Han was just a fucking asshole for no reason seemingly out of nowhere. (Basically telling Smoke to fuck off because they're not related by blood for NO REASON WHATSOEVER lol). He just spills that he let his father die because... Power? I've seen some people say they liked his voice acting but I thought it was too much and just cemented him as an edgy asshole and nothing more. I can't remember the last time such a popular character has been so mindbogglingly terrible in the story.
A lot of people were disappointed by Kitana's role, but I didn't think it was bad. They wanted to give Mileena the spotlight this time around, and it worked. Kitana was still fine. She was portrayed well, she just wasn't the star.
Overall, yeah, it was pretty good. It's a shame it wasn't four or five chapters longer, I feel like it would've tied everything more neatly, but this is still the best story mode they've done since MK9 imo. The tone was better, it took itself less seriously, and it did feel like a love letter to the series as a whole. Looking forward to the expansion.
