I'm glad. I wouldn't have thought to complain, but I'm glad they changed it.
The seating makes you so up-close to the action, especially the kids. Having a man punch a woman, even though they are equals and she's punching just the same, is just weird to see. Heck, someone punching someone, regardless of male/female, is weird to see if you haven't sat down around a boxing ring!
So I'm glad.
It was the "tiger god" that had my son get up and leave the kids seating area, not the punching, but I was actually surprised he wasn't more upset by the hitting (we know it's stage hits, but he's 4, ya know?).
