Film series aren't new (my hatred for the word 'franchise' being used in this context is on record).
I think "franchise" best applies to modern ganre-films that are plainly and statedly trying to launch a connected series of films.
Carl Lemme wasn't trying to start a "Dracula" film series.
Kenneth Branaugh is plainly trying to start the "Thor" series, happy meal toys, cartoon spin-off.
