Personally I think it was because there were three kinds of episodes...
sad ones ... with morals to the stories, a happy ending, etc. Examples: Homecoming, Developing, Memphis.
Funy ones...simply for comedic purposes. Examples: How Much Do you Love Your Kid, Gabe's Story.
And suspensful ones...One Night at Mercy, Sunrise, etc.
I think most people wanted to see SUNSPENCFUL and SCARY episodes. Not funny, or sappy episodes. Who watches Twilight Zone for comedy? That's my opinion.
