This season seems a bit cheap and lazy and ill-considered, like you have no idea how to take this plot to the next level, so you turn to death, random character, and thin twists of fate. And we are supposed to buy it in the name of good entertainment. Well, killing our favorite people and refusing to give the others a break is, at the very least, uninspired.
Does cancer belong as a storyline in entertainment television? Admittedly, if done well, it can provide important education. The risk is that if a television show gets one detail wrong, it can't correct it, and that might be the detail that we believe to be true and important and real. Worse, though, is the stress a show can add to a patient's already stressful life.
