The WarCraft movie flopped because WarCraft 1’s plot isn’t that great when you view it in context with the later lore. All the ‘context’ to WarCraft 1 works in hindsight because the events of WarCraft 1 have already occurred.
The WarCraft movie tried to do WarCraft 1 but with all the retcons present, and the narrative doesn’t work then.
If they absolutely had to start at WarCraft 1, then it should have just been WarCraft 1. Orcs were evil, Medivh was just a psychotic sorcerer Lothar had to put down, Llane is assassinated without ulterior motive.
Trying to marry the “Noble Savage” Orcs for WarCraft 3 to the narrative of 1 for a major motion picture was total folly. Hell, I’d say Warlords of Draenor proved beyond the shadow of a doubt that you can’t really do a WarCraft media pre-WoW because it’s kind of impossible for the Orcs not to be villains.
This isn’t me being Alliance main pilled here. The Horde routinely is the problem with the WarCraft narrative because while it’s stated they are an alliance of convenience to protect against predation , even within the bounds of Vanilla World of WarCraft, the Horde quest experience involves a willful cleansing of a established people from their ancestral lands to give the Horde “breathing room”.
