Within most thirty minute comedies, there are two types of characters: There are characters that appear to us fully formed, and there are the characters that are forced to undergo growth and change for whatever reason. Some shows have mostly fully formed characters, while others have main characters that require change. Shows like Modern Family don’t require much character development because we were introduced to the characters as complete human beings. With the exception of the children, you are going to see very little “changing” from the characters on that show. As a result, an episode of Modern Family doesn’t require you to invest a lot into the characters. You can just sit back and watch them be funny. You may be completely enraptured by Gloria’s baby storyline, but it’s not a prerequisite for appreciating the humor in her “singing” to her unborn baby.
