It’s been done
I watched a teaser for a movie I’m looking forward to seeing later this year, and accidentally got sucked into the comments.
As a rule, I try to ignore comments on the internet. Wiser people than I have written extensively about why some of the worst humanity has to offer seems to congregate in the comments sections of articles and the like. Sometimes, on some sites, you can’t help be see at least the first few comments while you’re looking at the actual content.
This comments section began with someone writing a long rant about how the movie, and previous entries in the related franchise, were not original. They had borrowed this element for an older series, and that element for an older movie, and so on and so forth.
Except, of course, none of the things he cited had been original in their use of those elements, either.
Humans have been telling each other stories, constructing various finds of flights of fancy, for tens of thousands of years. Every twist of plot has been thought of, in some form, thousands of times before, for instance. Technology and cultural changes allow some of the details and contexts to change, but in some ways only on the surface. If you abstract any idea out far enough, it becomes a trope or cliché that’s been around for ages.
Which doesn’t mean that it isn’t possible to distinguish between a genuine effort to tell a story that is yours, and a lazy copy of someone else. But it does mean that pointing out some element or bit of a story “has been done before” isn’t saying anything terrible profound.
And certainly not original.
