Being that I saw the original Scream around the ripe age of 11 or so (it was all the hype in fourth grade), it took me some time to understand the “meta” aspect of the film.
Eventually (after seeing Scream 2, the only sequel I would see until now), I would get the references in the original as I would have seen most of the movies the characters have talked about. Thankfully, one does not need to see any of the other sequels to understand the newest Scream film (technically, “Scream 5”).
Nothing else to say
