I am seriously wondering about what prompted some of the new shows in the fall schedule.

Once Upon a Time. A woman travels to a town where fairy tales are real.

Poe. Edgar Allan Poe as a sleuth in 1840s Boston.

Partners. Two female police detectives who are secretly sisters.

Awakening. Two sisters face off during a zombie uprising.

Ringer. A young woman on the run hides out by posing as her wealthy twin sister, who has a bounty on her head. (This is a big year for sisters.)

Tagged. A comedy set in a coroner's office.

Well, you get the idea.
