This week's most relatable comment from Japan on Sparks of Tomorrow

“Making things and running experiments as a student is so fun! The music's lovely too 🎺 — and the way they show the glass changing under heat, the thickness, the transparency, the light, it's all drawn so well.”

学生の時、物づくりと実験楽しいよね! 音楽も素敵です🎺 ガラスの熱変化、厚み、透明感、光など描写も良いですね。

“The animation and direction are consistently good, sure. The story's just not interesting. It got adapted because it's their own in-house light-novel label, not because the source material was actually up to Kyoto Animation's usual bar. Their in-house light-novel adaptations have always had that problem. Violet Evergarden might be the only one you can call unreservedly good.”

安定して作画と演出は良いんだけどね。単純に話が面白くない。自社レーベルラノベだったからアニメ化したのであって、本来京アニがアニメにする水準の原作じゃないと思う。 京アニの自社レーベルラノベアニメは昔っからそういうとこある。手放しで良いと言えるのはヴァイオレットくらいじゃなかろうか。

  • The animation and direction are consistently good, sure. The story's just not interesting.

  • Personally I love how understated and slow it is, but I guess that's not for everyone…

    淡々と進んでる感じが個人的には大好物なんだけど、万人受けはしないのかな…

  • Once the mismatched visual style starts bothering you, it does get hard to focus on the story itself. The sudden shifts into a different art style or texture come across as bold and interesting to some viewers, while for others they break immersion and just feel off. I think that's a big part of why opinions on this show are so split.

    表現のチグハグさが気になり始めると、どうしても物語そのものに集中しにくくなると思います 急に絵柄や質感の違う映像が入る演出も、挑戦的で面白いと感じる人がいる一方で 没入感を途切れさせる違和感になってしまう人もいる そのあたりも、本作の賛否が分かれている大きな理由だと思います

  • I thought the music sounded distinctive, and it turns out it's a brass band 😊 — of course it is, this is the studio behind Sound! Euphonium 😅

    音楽が独特だなーと思ったら、吹奏楽なんだね😊 やっぱユーフォの京アニだなと納得😅

  • It's a pretty experimental show, isn't it. Becoming "a different Kyoto Animation" may have been something they eventually had to aim for, but I can't help feeling that losing so many of their staff in that incident plays a big part in it. I'm hoping they use this "experiment" as fuel to grow even further. (Maybe it's deliberately experimental because the theme itself is "invention"…?)

    かなり実験的な作品ですよね。 “これまでとは違う京アニ”はいずれ目指さなくてはならなかったのかもしれませんが、やはりあの事件によって今までのスタッフさんたちを失ってしまった事が大きく関わっていると思わざるを得ません。 今回の“実験”を糧にして、京アニがさらなる進化を遂げるのを期待します。 (もしかしたら“発明”がテーマだから“実験的”な作品にしているのかも…?)

  • It IS good, though. What's your definition of "good" anyway? Flashy? Moving? Also — did you even need to post that?

    おもろいだろ お前の面白いはなんだ? 派手か?感動か? てか書く必要ある?

  • Thank you for the wonderful breakdown. I can't help but feel Anichare's love for Kyoto Animation in this. Hope this anime gets its moment in the spotlight. (^_-)-☆ Since it's about electricity, maybe it'll give us a real jolt? All depends on where the story goes from here.

    素晴らしい解説、有難うございます。 アニちゃれ!さまの、京アニへの愛を感じずにはいられない。 この、アニメに、スポットライトが当たるといいですね。 (^_-)-☆ 電気だけに、ビリビリっと、させてくれるのかな? 今後の展開に、かかっていますね。

  • The BGM in this scene is great too! I got into Kyoto Animation through Sound! Euphonium last year, so this feels like a reward of an anime (plus Sora Amamiya's in the cast).

    このシーンにしてもBGMが凄く良くて! 去年ユーフォから京アニにハマった自分にはご褒美のようなアニメ(雨宮天さんもいるし)

  • A good show isn't about the animation. That's it.

    面白い作品は作画じゃないからね。それだけ。

  • Engineering, I'm guessing? Rooting for you — from a former engineer.

    工学部かな?応援します(元エンジニアより)

  • It's a carefully crafted show, very Kyoto Animation, but the plotting — whether that's on the source material or not — feels convenient, and it bothers me. There's no emotional core to it yet either, nothing like Sound! Euphonium's "I could die from how frustrated I am."

    京アニさんらしい丁寧な作り込みの作品だが、原作なのかストーリーの構成がご都合主義でそれが気になる。ユーフォみたいに「悔しくて死にそう」みたいな話の核も無い。

  • No matter how hard it looks, I can't help but admire "making things."

    どれだけ難しくても〝ものつくり〟には憧れちゃう。

  • I get "the facial acting gets in the way." Kyoto Animation doesn't need that Fujio Akatsuka flavor.

    「顔芸邪魔」はわかる 京アニに赤塚不二夫風味は要らない

  • So what'd you pick? Tell us.

    何にしたんだい?いってみ

  • I'm watching this as a story about Kihachi pulling himself out of a depression triggered by losing his brother, or something like that, so I don't think I can really judge it until the finale. Violet Evergarden had that same "who even is this person" feeling around episode 3 too, if I remember right (and of course there turned out to be a real reason for that, plus actual growth).

    喜八が兄を失った?事から鬱状態になってるのを立ち直る話かなと見てるので、結局これも最終話まで見ないと判断つかないかなと思ってます ヴァイオレット・エヴァーガーデンもちょうど3話くらいのころは、ヴァイオレットがなんだこいつ感ありましたしね(当然そういう理由付けはちゃんとあったし成長もした)

  • Excited to see how Kihachi's catalog keeps growing out of this.

    これを基に喜八の目録がどんどん広がっていくのが楽しみ

  • I'm following it on TV broadcast, but I wonder if this is a show whose intent only becomes clear once you rewatch it all in one go after it's finished. The problem is, the only way to do that is Netflix. There's a real chance it just fades away without ever getting the reappraisal it deserves.

    テレビ放送で追いかけていますが、全話終わったときに改めて一気見すると意図が分かる作品なのかな。でも、その時に障害となるのは配信がネトフリだけということ。結局再評価してもらえずに消えてしまう可能性が高い。

  • I really love this scene. I'm a sucker for watching friends grind through building something together!

    このシーンとっても好き 友達が一緒に何か作るために協力して頑張るを見るのは大好き!

  • It feels like the direction crams in so much that nothing actually leaves an impression. What it needs is direction that's actually trying to entertain.

    演出が詰め込み 過ぎて何も 印象に残らないという感じ 楽しませようという 演出が必要では

  • When does this actually get good?

    いつになったらおもしろくなるの

Editor's note

Kyoto Animation's return means the Japanese comments here weigh craft heavily. On a behind-the-scenes clip about a single invention scene, the top reply came from someone who says that scene influenced their choice of university major — which is roughly the reaction KyoAni fans hope for.

It is not unanimous. A Japanese review channel asked why the show splits its audience and its own comment section proved the question, with the most-liked reply arguing the art is carrying writing that cannot keep up.
