The first ad was better. I know this was made for a Japanese audience but surely evenly the Japanese would prefer to listen to the nostalgic sounds of the Mario games over some cringeworthy pop music.
As for the land, it will certainly be aesthetically busy and I'm anticipating quite a bit of kinetic movement. On the other hand, construction footage shows quite a few static props that I worry will look jarring next to the moving ones. On the whole the theming looks a bit cheap and plastic-y due to the nature of the IP, but the kinetics may help quite a bit.
