Because people want to watch something that makes them feel good… Real life doesnt have beautiful doctors with perfect bodies, hair and makeup either. And the light is not turned down and romantic. Lols.

And I kind of like the story. Imagine if you actually had a genius doctor that would always be right. The hospital wouldnt fire him, or maybe they would, if they dont care if patients get better. In real life, maybe more money in keeping them sick.
