The ABC television drama Boston Legal is one of my favorite programs. The show features quick, intelligent dialogue and great performances. Producer David E. Kelly has used Boston Legal as a platform to speak out on a number of issues over the last four seasons. Each installment walks a fine line between entertainment and political/social issues such as the Iraq War, global warming and Hurricane Katrina. Tuesday night’s season premier titled “Smoke Signals” was no exception. In this episode, Kelly tackles big tobacco.
