Your point came through clearly to me. Shared tropes or setting do not make identical stories and, in fact, often enhance them as a counterbalance or familiar thing to compare against.

A wise friend of mine once said, in regard to "ideas are nothing; execution is everything": you can tell a thousand artists to paint a portrait of an Italian woman with a countryside landscape behind her but, good or bad, none of them are the mona lisa.
