On September 27, 2026, an article was published on the Chinese portal site Sohu, introducing that the "Detective Conan" 30th-anniversary work had surprisingly received harsh criticism.

The article reported, "Recently, the 30th-anniversary special TV anime 'Detective Conan: Case of the 30th Murder' was broadcast in Japan. Because the work was introduced as 'the most luxurious all-star cast in the series' history,' it had gathered great expectations from many fans. Not only main characters such as Edogawa Conan and Mouri Ran, but also police officers from various prefectures gathered, and the broadcast time was approximately 2 hours. Large-scale action scenes akin to a movie were also included, and it was attracting attention as a work aiming for movie-level quality. However, once it was actually broadcast, the evaluations completely changed. Harsh comments from viewers followed one after another," the article conveyed.

Furthermore, it stated, "While police characters from various regions certainly appeared, many of them had screen time of only a few seconds. Some characters only appeared for an instant, and even popular characters like Akai Shuichi and Amuro Tooru had almost no significant scenes, leaving an undeniable impression that only the promotional slogan of 'luxurious collaboration' took precedence. Additionally, while some action scenes were relatively good, in scenes where a large number of people appeared simultaneously, the animation quality was noticeably inconsistent, and there was little sense of surprise elements or special direction befitting a 30th-anniversary work," the article reflected.

It further pointed out, "The core of the story was a murder case revolving around counterfeit money, with a grand scale touted as a 'major incident that would shake the nation.' However, the deduction part was greatly simplified, the foreshadowing was poorly laid out, and the culprit's motive was weak. Even when the truth was revealed, there was no great impact, and there were many scenes where the action sequences looked like 'explosions for the sake of explosions,'" it criticized.

It also explained, "Regarding Takeharu Sakurai, who was in charge of the script, it had previously been pointed out that his understanding of the original work was shallow, and in this work too, dissatisfaction concentrated on the character portrayals. The handling of the Detective Boys and Professor Agasa was sloppy, and in particular, the scene where Ran makes a remark implying 'connections' to Suzuki Sonoko drew criticism for being a portrayal that damaged their friendship," it elaborated.

Following that, it stated, "Although it was a 30th-anniversary work with great expectations, it ultimately ended with the assessment that it was a work lacking substance. It is no wonder that fans who have followed the series for many years are disappointed that a milestone 30th-anniversary work turned out to be content like this," it concluded.

Furthermore, on the Chinese SNS Xiaohongshu (RED), harsh comments were posted, such as "It was a bit disappointing that my favorite characters didn't appear, but now I'm glad they didn't," and "Honestly, the moment so many characters appeared, I knew the story would be bad. What kind of culprit would require such a large-scale mobilization?"

Additionally, voices of disappointment followed one after another, saying, "I had a bad feeling, but it was really bad," "It was really tough to watch. The story was a mess, and in the end, they forcefully concluded it with a deduction, so I stopped watching halfway through," and "It was incredibly boring. I hadn't watched 'Detective Conan' for about 8 years, but the trailer for the 30th-anniversary work looked really exciting, so I watched it, and it was truly terrible." (Translation/Editing by Iwata)
