Many people really enjoyed MVA at least in the west and it's understandable why, it's an arc focused on the main villains and not on the main protagonists which is something very rare to see.
The arc gives really good character focus to the villains mainly Shigaraki, Twice, and Toga, we also get to see their backstories, and the arc also sets things up for the war arc and beyond.
It's an arc that is not only important for the villains but also important for the story, so again it's understandable why many people including myself not only wants to see this arc in the anime but we also want to see a proper adaptation of it.
Also I want to see more of Re-Destro in the anime.
Yeah, but I don't think they really care necessarily for specifically western audiences. Also, whose to say that MVA is going to be bad?
Like, this is a lot of drama for an arc that hasn't even aired yet.
It gives good character focus to Shigaraki, Twice and Toga, true. It only really works well, or is only really good for Shigaraki and Twice though. I still did not give a shit about Toga after that arc, also, the other three villains still suck.
Like, for me, MVA is weird. Outside of maybe Twice, we are not supposed to really care or sympathize with the villains as much as we are to understand them.
In that sense, I found it a little bit of a chore at times. This is not to say it wasn't interesting or didn't explore the themes, but its also really hard to care about literal mass murdering assholes fighting other assholes. Its kind of difficult to get invested in that. Aside from Twice, I don't think I would have at all cared if the entire league died from getting steam rolled with a road roller, because they aren't really great personalities to invest in.
I know this is the stock criticism of the arc, but I think its one that still holds true.
Still, seeing Shigaraki blow stuff up was fun. Hope thats well animated at least.
