It seems that in America they so quickly cancel shows based on ratings immediately opposed to long term viewers discovering the show.
The inevitable American pilot can see a program be a hit or miss from the very second it airs without consideration of the story they leave unfinished and the audiences they let down.
Of course this happens in the UK but the shows aren't as good so you soon forget about them.
This happens too often. Keep making great shows, just reduce the insane budgets...
