I'm only through the first half an hour and find it hardly child friendly. The speech is to fast and the innuendo to the lewd is inappropriate for kids. Fortunately most won't get it. I am a fan of Emily Blount and who knew she could sing so well.
All other aspects of a musical check the boxes, costumes, background, animation quality voices, choreography they missed the mark on content and sheer speed of the dialogue. Can one really expect a kid to follow this? Ben Whishaw is ineffectual and disingenuous.
