I noticed that people have created ghostbusters-1984 and ghostbusters-2016. I've edited the ghostbusters tag to make it clear that it can be used for the 2016 movie as well, but I'd prefer to stop the tags before they start if we decide against them.
In this instance it's perfectly possible that users may wish to have answers that relate specifically to the original film series and/or the rebooted film (which may yet spawn a series)
To that end, we should have tags for both sets of films as well as an overarching franchise tag that encompasses the two film series', the two TV series', various novels and other licensed properties.
Given the low usage (only 18 questions) of the original tag of
Ghostbusters we should be able to manage with just one tag for the entire franchise.
Some of our other tags that span different mediums (
Super Mario Brothers (x9),
Guardians of the Galaxy (x79)) use only a franchise tag.
.* If the new franchise does spawn a mass of questions then it is possible the need for a new tag would arise. However, in its current state the answer should be no.
