How did Molière and Shakespeare each push the boundaries of genre?

What will be an ideal response?

• Though Shakespeare's later plays truly defy categorization based upon genre, all of his plays combine humor and darkness using one to comment on the other through characters and subplots. The comic and tragic do not just inhabit the same plays; they seem to coexist in each moment and to threaten each other's worlds. Some critics write that he mixed genres to cater to the tastes of his popular audiences, but others believe he mixed genres to allow his plays to provide a true picture of nature, which does not follow easy categorization.
• Molière's plays pushed comedy past the light entertainment of his day into probing studies of human excess. In Molière's plays, the world is set right in the end, but unlike other forms of comedy, his characters do not find happiness unless self-understanding is gained, adding the recognition moment of tragedy to the comic form.
