"People want laughter when they see a show.
"The last thing they're after's litany of woe."A Theatre trope, but could be applied to other media. People who are attempting to get a big break with a musical that they are involved in, usually in a writing capacity, are often advised that they should do something funny, or light at the very least, because Serious Business doesn't sell without a creator's reputation to give people an incentive to go. Contrast True Art Is Angsty, which reigns supreme in most other media (including non-musical theatre). Compare What Do You Mean, It's for Kids?, when material aimed at children is criticised for being too dark.
