I heavily dislike Satsuki Vs. Kevin but this is just the facts. The absolute vitriol it gets is absurd, and is mostly down to perception more than anything. People feel safe shitting on it, because it's considered to be "debunked" and therefore an easy target to relentlessly pick on. Combine this with the fact that the match is generally just weird and unappealing to a lot of people, and you've got the perfect storm for a MU that's easy for people to shit on. MU's with equally, if not more thorough take-down posts (Gwenpool Vs. Haruko, Drakkon Vs. Enerjak, Shirou Vs. Noctis) still persist because they are generally appealing in ways that debunks can't really stamp out. Meanwhile, I feel Kevin Vs. Satsuki's outward "weirdness", for lack of a better term, makes it extra vulnerable to being dismissed.
