Contrary to what protestants in general, and American ones in particular, want to believe, this isn't usually enough by any means. You see, any major literary author or work, such as Shakespeare, requires a ton of research to be properly understood, so much so you have entire academic departments dedicated to properly analyzing them.
What a waste. It would be much better to put on an entertaining show based on those works.
What do people get out of this "understanding" anyway?
