Does an original title help or hinder finding readers? I don’t know, but I can think of some pros and cons. Pro, your book will come up whenever anyone searches on that title. Con, people may choose one of the others instead of yours!
Personally, I feel an original title implies that your story, too, is original. On the other hand, if it’s deliberately surfing the wake of a best-seller, then it makes sense to show similarities in the title, cheesy though that may be.
