It seems like a good set-up for a screenplay in any genre.
For example, my friend’s idea of a romantic comedy based on two people who meet via an internet dating service, connect on New Year’s Eve, but become estranged and reconnect on the next Blue Moon, 20 years later.
I invite you to come up with a one-paragraph plot for a screenplay based on the New Year’s Eve Blue Moon idea and submit them to me via firstname.lastname@example.org. I will post my favorites.
Good luck and happy writing.
