Either the high jumpers clear the bar or they don't. In the arts, what is good is always a matter of opinion. That's why there are 50 different recordings of Beethoven's 9th Symphony on the market. There are many reasons you might be in honest disagreement with good judges. Judges look for performance excellence not entertainment value.
Judges look at how well a show is performed.
They pay little attention to how entertaining it is. A skilled performance of a dull show will score better than a mediocre performance of an interesting show. Audience members are impressed by entertainment value, as well they should be. They should not compare their opinion of a show, which was based on how well they were entertained, with the opinion of judges who were evaluating how well specific skills were demonstrated. Contest guidelines require that bands demonstrate certain specific skills in performance.
