The imaginary invalid, the rich Argan, surrounded himself with people that only want good for him. They accept the old man as he is and all they want to do is cure him from his mental illness. They try to show him that his illnesses were coming from his head and unmask the doctors trying to make money off of him.
Even though the old man almost chased everyone away from him, the comedy has a happy ending. Moliere sent an important message with his work and also showed his artistic skills. The work is also entertaining, easy to understand, filled with humorous lines and witty.
