That said, there are also plenty of Slam Dunk fans who do watch a lot of other anime as well, so maybe the kinder tone of the Japanese-language reactions has something to do with a broader awareness that The First Slam Dunk is being directed by Inoue himself, and it’s unlikely the series creator would be accepting of the change to CGI, let alone be so closely involved with the movie, if he didn’t think it was a viable choice.
On the other hand, even though Slam Dunk is undeniably an anime series, being a Slam Dunk fan in Japan doesn’t necessarily mean someone is all that into anime, or so fiercely enamored of hand-drawn animation.
In other words, if someone is a non-Japanese hardcore Slam Dunk fan, odds are they’re also a hardcore 2-D animation fan, making the switch to CGI for The First Slam Dunk feel like a downgrade.
“I’ve loved Slam Dunk for so long, and I’m grateful to be able to experience new anime for it in real-time.”
