>>99451157 said, Injustice was created to be completely edgy in the first place. With Ultimate the only edgy parts were arguably Millar's, and compared to Loeb or whoever came up with the backstory for Injustice, Millar looks like a more competent writer.
Ultimatum in turn actually ruined something while Injustice started out "ruined" to begin with and people had low expectations.
Additionally, there's a vast writing quality difference between Injustice and Ultimatum. No matter how dumb Injustice got they didn't reach the consistent number of stupid things within Ultimatum, or maybe in Injustice it was more spread out.
