What you're describing is a fairly common occurrence with story-identification questions.
Question 1 ...
Question 1 - I'm thinking of a film that has metal people from the future trying to kill a woman named Sally.
A. This is 'The Terminator'. The metal people are called Terminators and the heroine is actually called Sarah.
... is still a dupe of Question 2 ...
Question 2 - I'm thinking of a film where a psychiatrist interviews a man from the future and doesn't believe him
... even though none of the points raised in Question 2 are addressed in the answer to Question 1. That's just how we roll, I'm afraid.
We also have a policy
Closing Story-Ident questions as duplicates (where there's no acceptance)
to prevent potential dupes being closed until there's an agreement from the OP that their question is actually a duplicate.
