If it’s that big of a hurdle then why is anime so popular with western audiences? I don’t think the problem is that Japanese storytelling is so different. I think the problem has been the same as it was with comic books adaptations for so long. The Hollywood studios didn’t respect the source material and wanted to make a lot of unnecessary changes.
All it really takes is someone who knows and respects the story they are trying to adapt with the budget to do it justice.
