Too bad the fans will never ever accept this.
To draw a parallel with the movie industry, this is also why the Michael Myers character (from the Halloween film franchise) can not and will not die / disappear.
Halloween (franchise) - Wikipedia
Starting with
Halloween III: Season of the Witch, the franchise was set to follow a different path than the one which was started (and ended) in the first two films. Therefore, the Michael Myers character was never to reappear ever again. Because his story had been told.
Now guess what: of course, the fans complained. Therefore, and also because the film was a commercial failure, the character was featured again as the main antagonist/protagonist, starting from Halloween 4 onwards. The fourth film was adequately titled Halloween 4: The Return of Michael Myers, and his name will even be cited in the title of the two films that followed the fourth opus of the 'series'.
It is a real pity imho. The producers of the franchise were willing and ready to explore new territories, with plots, storylines and characters unrelated to each other with each new film. And they might even have done an interesting job at it; imho, Halloween III has an interesting and clever twist about what the whole Halloween tradition really is about. And some of the film's (many) flaws and (numerous) plot holes surprisingly contribute to make it an overall enjoyable B-movie iirc.
Again, too bad the fans only cared about
one specific character only...
So be all prepared for:
- Warcraft 4: the Return of Thrall
- Warcraft 5: the Revenge of Thrall
- Warcraft: the Curse of Thrall
- Warcraft H20: 20 years later
- Warcraft: Resurrection
..and I am not even mentioning the mandatory reboot of the whole series that will follow, featuring...
...
(drumroll...)
...
...old Thrall, old Jaina and whoever / whatever else existed in the original Classic Warcraft / Warcraft II Lore (
Alleria Windrunner, anyone?)
...all because the fans will want it that way.
