At the risk of coming off as a SMC whore, I will say that this is a MUST take course.
Most of us don't realize there are ways to handle the exposition beast, so we plod along, not knowing that we don't know. And our writing suffers for it.
An easy tell for Readers/Agents/Managers between amateur and professional screenwriters is how they use Subtext, work Scene Transitions and handle Exposition. Enlighten yourself.
