"Conflict is the basis of drama. I guess that goes back as long as time has existed as far as mankind is concerned, dating back to the Greek tragedies or the Old Testament. And violence is a form of conflict, so whether that's catharsis or whether that has some socially damaging effect on audiences - I suppose that would just depend."

All good dramas are rife with conflicts, and the conflicts have to be resolved. What I think is so great about a show that takes place in a hospital is that you have so many different people with different needs. Sometimes all those can be in conflict. The drama of Heartland also comes from the group of people waiting, and they are sometimes agonizingly waiting for a new organ for their body in order to survive. So the show is so much about survival, which creates a sense of urgency to get the organs. I think that sense of urgency is probably the most prominent dramatic quality to the show.
