As far as I'm concerned, they took the easy way out. They came up with a concept that enabled them to basically shoot the show without coverage. So, while I enjoyed the show, it wasn't what I thought it was going to be. In other words, they could make mistakes and you'd never know it, because of the concept. In 1953 and 1956.
Shot totally live with full coverage, just like a movie.
And they were both brilliant. As good today as they must have been back then. And when you think of the danger inherent in this, they're doubly amazing. But most of all the writing and the acting. And shown once.
