No fewer than three big-budget Hollywood films based on Japanese originals opened this year: "Alita: Battle Angel," "Pokemon Detective Pikachu" and "Godzilla: King of the Monsters." While all three were still being promoted, "Gundam" and "Akira" were green-lit for production by Legendary Entertainment and Warner Bros., respectively. An adaptation of Sega's Sonic the Hedgehog video game will be out in November, followed by Hollywood takes on Capcom's Monster Hunter next year and Nintendo's Super Mario in 2022.

The highest grossing anime feature ever, Makoto Shinkai's 2016 "Your Name.," is being remade as a live-action film, produced by "Star Wars" reboot king, J.J. Abrams. Hollywood renderings of "Attack on Titan" and the iconic mascot Hello Kitty are also reportedly on the way.

But so far, Hollywood's versions of Japanese content have received mixed reviews at best, with some earning respectable but not remarkable box-office numbers. Most fans return to the original stories and wonder: Why can't they get it right?
