There are a large number of Anime adaptions of games that prove large portions of this video to be blatantly false.
Japan has consistently put out quality anime adaptions of games in both series and films for decades. They've proven beyond doubt it can be done well.
It's just that western film studios can't figure out how. It's largely got to do with the inability to produce faithful adaptions.
They always alter things for the sake of bringing something to film. Doom's demons are in fact a virus, Koopas are dinosaurs, something is different because studios are under the misguided impression that people don't want the same thing they played on their gaming system.
That's exactly what people want. The exact same thing they played, or a continuation of it, but with much prettier visuals and action sequences that would be extremely difficult, if not impossible to recreate in gameplay. Proof of that is in the only well received segment of the Doom movie. The first person sequence that most closely replicated the game environment. It was universally praised as the best segment of the film [but wasn't enough to save it either].
This is exactly what the most successful and well received anime adaptions do. They are as close to the game's designs, plot, and tone as they can possibly get most of the time.
Western studios haven't figured that simple fact out. It's why they repeatedly fail to create a successful game adaption. They're always looking for that new and different angle to draw audiences in when that's actually the exact opposite of what people want to see.
Sure, focus groups of people looking for stuff to complain about say otherwise, but those surveys are notoriously not trustworthy and easily skewed by how the questions are phrased.
People want the same shit they saw when they played the game, but more realistic looking and visually detailed. They want the same characters, the same plot or continuation or bridging of plot, and they want it to look better than it could with current gaming technology.
Once Hollywood figures this out, we'll have another genre boom on our hands just like the one we have now with comic book movies.
