I've already written how comedy--and scripts--should flow and circle back around on an idea. The reverse of this is equally powerful. Give your character a vice and help them overcome it. Then, when you need your audience to know the full extent of a crushing situation, drop the vice back into your hero's life. A relapse is a terrible blow, and one to which most of us can relate.
A Problem Worth Drinking Away?
Give you audience something to root for, and you'll have them by their heartstrings when you tear that away from them. The beauty of this is that now they can't wait to see how--or if--your character will ultimately overcome.
