I get a kick out of The Big Bang Theory. A lot of the gags are oversimplified, but they are all relatable. Who doesn't like Sheldon, in spite of his horrible personality? The writers strive to show you why he is the way he is and occasionally open his vulnerable side, a la "soft kitty, warm kitty, little ball of fur..."
The goal of many writers is to accomplish just that. Portray a flawed character and make them likeable in spite of themselves. That might be one of the most challenging things, because as people relate to people, they tend to divide them into categories without taking the time to see beneath the surface. Writers need to take that extra look and find the redeeming quality.
I'm married to an engineer, so in many ways, Big Bang is even more relatable. Children defy logic. Women can, at times, defy logic. Try and explain that theory to an engineer. This does not compute. That can't possibly happen given the variables, like Sheldon so often doesn't understand why people don't see the world the way he does. That can make things extremely frustrating for all parties in the real world. As an author/writer, it can be fun to unlayer the neuroses. It's called conflict. Works in novels and on TV, even if those personalities make the real world a challenge some days.
So now I have to explain to my "Sheldon" about why you can't argue with a woman who is coming off a stressful deadline and expect it to make sense. (And I'm giggling as I share with you that even he doesn't always make sense when stressed.) Real life, as opposed to a novel, requires faster conflict resolution. It might make for good reading to let the conflict go on for the next 100 pages in a novel, but in the real world, there aren't many heroes or heroines who will (or should) wait that long.
