The music seems to be a combination of Baroque Hoedown and some pop song that I agree seems wrong, but it doesn't totally ruin it for me.
But to me, MSEP has never been about the specific characters, and always about the presentation and technology. I'm getting tired of the overuse of flat panel LED screens, yet as long as the characters are ones we'll recognize and remember, I don't think it matters whether they're 50, 30, 10, or 5 years old.
I'm basing this on
YouTube videos. I suspect I'll never have a chance to see it in person.
