Let's take cars_(disney) for example. What copyright tags should be on a post with only one character which is only present in cars_3? Should it only have the cars 3 tag or should it have the tags for the original and the sequel, in this case cars_(disney) cars_3?

in general sequels dont get separate tags. theres some exceptions tho. personally i dont think that cars movies need separate tags.

In movies like Cars, all same-named characters are actually the same character, and thus don't need different tags. The only time we need different tags is when there is a character or species that is different, for example: the lizalfos from Legend of Zelda.

This really is an interesting question.

I mean:

The Madagascar franchise:

• madagascar
• the_penguins_of_madagascar
• madagascar_3

Five Nights at Freddy's:

• five_nights_at_freddy's
• five_nights_at_freddy's_2
• five_nights_at_freddy's_3
• five_nights_at_freddy's_4
• five_nights_at_freddy's_world
• sister_location
• freddy_fazbear's_pizzeria_simulator

Dark Souls:

• dark_souls
• dark_souls_2
• dark_souls_3

etc etc etc.

we do this rather consistently.

and I mean, I can understand for something as detailed/complicated as five_nights_at_freddy's with probably literally 100 characters that are not in every single game..

but.. we do tend to tag sequels... I'm not sure we SHOULD but I think it's easier, as a general rule to say:

(movie_sequel) implies (movie_franchise)
(movie) implies (movie franchise)

but.. I dunno man.
