Jack Webb, for any virtues he may have had was the worst, one-dimensional actor of all time. He could gave been replaced with a cardboard cut-out with no loss of verve.
He did have some odd attributes.
He always talked in deadpan monotonous tone. He also walked without swinging his arms. I will say some of the episodes were very very good.
I remember one where this kid worshiped some comic book super hero. He had a big picture of his hero on the wall. When Friday caught him the kid started to weep. He went up to his hero poster and placed his face against it. when he moved away, the poster had tears in it’s eyes.
