Necessary as some of the redesigns might have been, I don't like a single one of them. Dhalsim and Bison look good, but that's because they've been left alone more than the other SF V versions of characters (looking at you in particular, Ken). I wouldn't call them redesigns. They're updated to fit the SF V art style, but that's basically it. The actual redesigns (again, like Ken) all look terrible imo.
I do hate most things related to SF V, but there's nothing blind about that. It's just my opinion, based on my experience with the game. I bought it, played it extensively, and I'm a huge fighting game fan in general. And now I'm at the point where, yes, I could write a book on all the things I thoroughly dislike about it
