Just wondering, how strong does a connection have to be, to be considered canon? Specifically, referencing movie events. Could any (serious) movie make out that one of the IPs exist in-universe (eg shoestring budget college films) or does it have to be of certain quality?
I don't plan on just making a movie that references Freddy Krueger (for example) and say "Yo I made a movie and got it officially licensed, add it to the timeline," I'm just intrigued when it stops becoming essentially fan-films and starts being considered canon
