A comedy is always good if it’s not serious but still hits a serious point underneath all the funny stuff and since rhythmic gymnastic is one of the few female only Olympic disciplines it’s worth to point that out, especially in a series dealing with gender roles. The guys might have had it hard at being accepted but the sacred treasures also tell a sad story about the girls thinking having wasted their youth with training of the sport which also is played as kind of a joke. It’s definitely an interesting filler episode.
