It would go over well with the older people mainly. Though my kids get a chuckle from some of the old cartoons shown on Boomerang. For me, watching old HB cartoons is painful, especially the ones that tried to be dramatic and many of them had horrid animation, even for their time, lol.
Still, H&B were responsible for my second favorite cartoon series ever, Tom & Jerry, so I would happily take my family to a park made in their honor.
