Re: Better if they had allowed main cast to die?
Has any TV show an episode that was beyond repraoch. I would dubt it.
But many shows seem to manage to drop bits in for a later play off. I.e B5, DSN. They had episodes which were self contained but maybe had an element that would have a later pay off.
On the continent of wild endeavour in the mountains of solace and solitude there stood the citadel of the time lords, the oldest and most mighty race in the universe looking down on the galaxies below sworn never to interfere only to watch.
