3) Avoid Overloading The Humor
Considering how often it’s been discussed at this point, you’d think the word “quip” was a newly-established curse word. This is due to the consistent bickering/one-liner-exchanging dialogue that’s present in MCU films becoming so popular in recent years. Ever since The Avengers, many comic book movies have adopted this system of comedy where many characters make jokes constantly at almost every opportunity. While Justice League doesn’t quite abuse this as heavily as it could’ve, it’s clear that it went too far with the inclusion of humor.
While everyone loves to have a good laugh, it’s important to not try and force one too often. This leads to an audience that grows tired of constant joking and eventually forces one to stop laughing altogether. Audiences are prone to laugh, but they can feel when a humorous moment is being forced onto them, too.
Justice League has plenty of funny moments, but there are a number of them that feel like they were added purely to gain a laugh and not because it fit the character. Flash seemed to suffer the most from this as he’s forced to joke constantly. While much of what he says is hilarious, it pigeon-holes him into the comedy relief character. Add in almost every other League member who crack jokes at multiple points, and you get a film that tends to lean too heavily on its funny side.
It’s important to remember that not everyone has to be “a funny character.” More importantly, someone who isn’t the funny character doesn’t automatically become the boring one, so don’t feel obligated to make them comedic. Allow them to conduct themselves in a way that suits their own characterization without compromise. There’s no harm in humor, but don’t feel a need to give everybody jokes for the sake of forcing a potential laugh.
