It's pretty clear that the Bolvar/Sylvanas cinematic was designed to get the audience hating Sylvanas and wanting her to die, to hype up a confrontation with her in Shadowlands.
But as we can see in the comments everywhere, people are hating Blizzard instead. Some people think that Sylvanas will get away with everything, some people think it's a girl power fantasy, others are calling it the worst cinematic ever and swearing off the franchise.
Is it worth it to make an audience mad about the story? Because I think it's driving people away from the franchise moreso than making people want to buy to kill Sylvanas.
