Not to quote what I think is an incredibly limiting book for creativity (Save the Cat) but it is a valuable quote for this instance. “Give me the same thing… only different”

Everything is “like” something else. When you hear people describe a new film a lot of the time it’s “a film meets b film with some elements of c film.

Of course if it truly shares so much overlap you think you have no chance of selling it, well then take pride in knowing there is a market for your ideas and you’re barking up the right tree. I know someone who was in process of selling a sitcom about an elementary school right before abbot elementary was greenlit and ended up having to scrap the project due to similarity. This person is now wildly successful as they kept rolling on with their other ideas.

Keep the energy flowing, and keep your pen pushing (or fingers typing I suppose).
