Mainly, I don’t think there is a “Video Game Curse” I think there is a Video Game STIGMA.
Back when the Warcraft movie was announced people began spinning a narrative about how it would be bad, before the narrative of the movie was even finalized.
The biggest flaw of video game movies (other than being made by Uwe Boll) is that they try to turn the interesting mechanics of a game in to visual and narrative devices. Duncan Jones doesn’t try to to do that. The action scenes don’t look like World of Warcraft group battle, they look like action movie scenes, and that is a good thing. Khadgar does make a joke about spell duration, but other than that we don’t see anything like cooldowns, or mana bars, because those things are mechanical limits of the game and not part of it narrative appeal.
I think that in the end, because the movie did so well in China, we will see a sequel. Fans and the public have seen the movie and expressed a huge amount of positive support for it. Critics might (might) actually pull their heads out of their butts and WATCH the second movie. It’s a little late to recant on unfair reviews of the first film at this point, but by the time we get to the third one, I think we will have seen an end to the video game movie stigma.
