It's a great interview overall and it's good to know that Chris is doing well and that he's recovered from his surgery and has gotten over his anxiety issues. I'm also glad for him to be able to experience the game as a fan rather than a creator.
I agree with a lot of what he says about having empathy towards artists and creators, because they are humans and they are putting themselves out there, which is a hard thing to do. Personal attacks, vitriol, threats, obviously these things are immature and pathetic, and they sure as hell don't make for effective or persuasive criticism.
However, I do think that valid criticism is important.
When they talk about The Last Jedi or Warbringers: Sylvanas, I think the you can't really deny that the creators missed the mark. If they hadn't missed the mark, the backlash wouldn't be so big. Where there's smoke, there's fire.
I think that Metzen gives Rian Johnson too much credit, and Metzen admittedly says he doens't know much about Johnson. Based on Johnson's attitude in interviews and other features, I really don't think he has the zealous sort of passion for Star Wars that Metzen generously assumes he must have. This is a guy who bragged about not having a vision for the films and making things up as he went along, and bragged about being hired to direct a new trilogy without actually having any ideas in mind. A guy who lacks creative vision doesn't deserve the benefit of the doubt as creator, especially for something as beloved as Star Wars. He has a responsibility to the fans to do better than that.
And when it comes to Blizzard, frankly, their track record post-Warcraft 3 hasn't inspired a ton of confidence in their storytelling. I've never expected high literature from WoW -- far from it, it's pulp fantasy through and through -- and I honestly like a lot of what they've done with the story, but they've missed the mark frequently enough that even I'm skeptical of their ability to pull off this story in a satisfying way, and I'm generally an apologist who gives creators the benefit of the doubt.
Sylvanas is perhaps one of the most popular characters in the ongoing Warcraft franchise, and given Blizzard's general inability to convincingly pull off heel turns since Arthas, I think it's completely valid that this story arc is setting off red flags, and fans have every right to be angry about the direction the story of their favorite character is going.
If Blizzard had consistently churned out stories that were universally acclaimed I might have a different opinion here. Obviously there's the possibiity that they have everything planned out and it will build to a satisfying finale that makes everyone happy, regardless of whether they're fans of Sylvanas or not. It's a possibility. Blizzard just hasn't earned my unwavering faith. I mean, even in the midst of this very story there are inconsistencies between media, with the game leaving out vital dialogue and details that would help to contextualize the story, and there's really no good reason for that to happen.
Obviously, that's no reason to personally attack someone, and certainly not to threaten them. There is a right way to level criticism. If you don't like the story and want to voice your opinion, choose your words carefully and enunciate your problems with it, make a persuasive argument. Don't just dismiss it or resurt to childish insults and threats. That sort of behavior is frankly pathetic and embarrassing.
