M*A*S*H offered real characters and everybody identified with them because they had such soul. The humor was intelligent and it always assumed that you had an intellect.
Some major writers have a huge impact, like Ayn Rand, who to my mind is a lousy fiction writer because her writing has no compassion and virtually no humor. She has a philosophical and economical message that she is passing off as fiction, but it really isn't fiction at all.
I genuinely liked all of the cast members very much. Steve had a wicked sense of humor. I remember Russell coming to my rescue, once. I watched Eric evolve before everyone's eyes. Maurice loved what he did, so. He treated his character with respect, down to the costuming.
Poor David Hume is dying fast, but with more real cheerfulness and good humor and with more real resignation to the necessary course of things, than any whining Christian ever dyed with pretended resignation to the will of God.
If you can get humor and seriousness at the same time, you've created a special little thing, and that's what I'm looking for, because if you get pompous, you lose everything.
A sense of humor... is needed armor. Joy in one's heart and some laughter on one's lips is a sign that the person down deep has a pretty good grasp of life.
