Considering the muddy new lore and the constant retcons, I think it is too late to make another Warcraft movie or even a TV show.
I always thought the WC series would be a better fit for an animated show, but then I fear it would suffer the Game of Thrones effect, which GoT suffered from lack of original material as the seasons surpassed the books and lacked an original storyline to base the new seasons from.
With the latest retcons muddying the lore, I believe that a WC TV show would decline in quality of storytelling. WC will be remembered for being wonderful games to play, but its story will be less than desired.
Anything created to that effect would likely cover previously-tread ground in greater detail, and for a more general audience. Things like the (good parts of) Arthas storyline, that are fully, indisputably Warcraft, and actually have a rich narrative with compelling, conflicted characters.
There’s so much stuff that is cool to us but isn’t acceptable high fantasy. All the Old Gods, for instance. In WoW, the Old Gods are among some of my favorite things. More Horrific Visions on the roadmap? I was giddy to see it.
But 99% of it is kind of just re-interpreted Lovecraft lore applied to the Warcraft franchise. Which is cool, because Lovecraft’s “latent, eldritch horrors” are freaking perfect always. But it’s still kind of re-imagined IP. Those kinds of nods and homages are littered and intertwined all through WoW. Which is good, but complicates things from an internal, cohesive point of view.
I personally loved the Warcraft movie, thought it was compelling, thought it was generalized enough but deep enough. Just don’t make an anime of it or something, plz.
