The Sims 4 moving away from its kid friendly themes?

I guess I'm old. I don't like the song nor the trailer. It doesn't inspire me to want to play Spa Day, (I really like the first trailer and the DLC and enjoyed that pack) and actually I don't understand what dancing has to do with going to the spa to get your nails done. I would have done a fancy restaurant scene with elegant people who live pampered lives and show their nails while holding their wine glasses and diamonds on their fingers etc. Or shopping with the nails as the focus as they flip through clothes or pay at the register....but I guess that is out since none of that exists in TS4. This doesn't make me think go to the spa and get pampered at all.
