One of the main themes of Cosi is the question of love and fidelity.

Lewis is hesitant to take on the role of director at first because he thinks of all the patients as mad but learns that they are ordinary people with different needs. It also shows the state of the mental institutions of the time in Australia. This is symbolised by the burnt out theatre at the mental institution.
