I didn't realize until after deleting the program that Judy Garland was in this. I'll have to look through the other reviews to find out where she makes an appearance.
It's an ensemble seemingly of all girls who are dressed in highly-sexualized costumes for the era and who use the gestures of tarty adult women. The "Hot Little Comet," was particularly sleazy, a 10- to-12 year old girl gyrating and scatting.
They dance well, but there is a feeling that they're dancing their little hearts out to avoid being fired. The enthusiasm is forced. I think that tap dancing in ballet toe shoes is tacky.
The little girl at the end is an amazing gymnast, but the performance goes on too long. It's also weird how instead of ending with a close-up or some kind of frame shot the camera just pulls away. I seldom consciously note camera shots so if I did it's because it was done particularly ineptly.
I agree that the Moon Man emcee is disturbing. The set-up at the start that takes them to the moon is also weird. The song the girl sings is not pleasing to the ear.
It's fascinatingly awful and repellent.
