I had a huge advantage when I started 50 years ago - my job was secure. I didn't have to promote myself. These days there's far more pressure to make a mark so the temptation is to make adventure television or personality shows. I hope the more didactic approach won't be lost.
It's kind of amazing how popular 'Grey's Anatomy' is. What other show can boast such an annoyingly sincere cast of doctors sniveling through such perfunctory love triangles?
