This has come up again with the "Nolan-", "Donner-", and "Burton-" continuity pages.
DrJohnnyDiablo posted to those three talk suggesting the be moved to reflect the first movies in the respective franchises. It is worth noting this can also be applied to "Arkham-" set as well.
Personally, I don't think that is a viable alternative since that winds up applying the one film title across 4 or 5 films.
While the "-verse" notation for each is firmly entrenched, I do understand that the origins as fan-created terms is a problem for some.
For myself, I have little problem with the current terms, but if they are replaced, I would lean towards:
- Superman (1978 Film Franchise)
- Batman (1989 Film Franchise)
- Batman (2005 Film Franchise)
- Batman (2009 Video Game Franchise)
