I thought the Injustice comics were very good. Their biggest limiter was the mandated format that each episode was very short but I never saw why some people hated it. So far as I could tell it was just some reaction to the idea of an evil Superman being inherently some "edgy" try-hard thing when in the comic they actually did it exceedingly well. He doesn't go "Zap! I'm evil now!" and start wearing a goatee like people make it sound. He loses Lois and his child and he decides to go further in making the world safe. It starts small and it escalates bit by bit. Unless we're talking about the movie adaptation which was impossibly short and does feel like that. But the comic is excellent with many good scenes. I liked his playing chess with Flash whilst debating gun control. It's key that the first two games Superman wins (Flash has only just learned). But by the end of the conversation, Barry is wining each time.
I go back and forth on Injustice and I think my main takeaway is that it does minor characters really well, but the main ones have to act wildly out of character (even within the story) to make any of it make sense.
Batman was written poorly. He is super hostile for no reason towards Superman. Yes, Superman killed his gay lover, but seriously Bruce, the man let off a nuke, he deserved it. What makes it worse is that he accepted Harley, an accomplish to a nuked city, into his gang like she did nothing wrong.
Wonder Woman is just her usual Flashpoint, cunt self. I am honestly tired of her just being a warrior and not someone with compassion. Bitch didn't even fall to the dark side, she started there.
Hal and Barry were far too passive for characters that could have easily prevented everything.
Nightwing's death was super dumb. Victor then siding with the people who got his leader killed made no sense as he was all Teen Titans this, Teen Titans that... I will let him off the hook for not knowing that Clark sent all his friends to the Phantom Zone, but he should have known by game 2. As for Damian, what more can be said, his usual insufferable personality was upped x10.
People typically complain about Jokerwank as a Batman villain caused Superman's downfall rather than someone like Lex (likely because they stole the plot from the Justice Lords). Joker nuking a city being the catalyst does harm the plot though. Harley should be irredeemable by most standards and Superman was incredibly justified in killing him to the point where Batman looks like a tard arguing against it.
The entire plot is just a bad remake of the Justice Lords from JL. I think Lex becoming president and killing the Flash was a much more impactful start to the regime, while eliminating Flash plot armor. The Justice Lords were also just more interesting and horrifying given they don't kill, but "rehabilitate".
