About Detective Conan TV Anime...
I want to start off with some facts about the anime series as it occurred to me that some people don't quite get what a manga-to-anime adaptation is.
#1
Aoyama-sensei is a manga artist. He doesn't oversee the anime production. The anime team is the one that decides what gets included or excluded in the TV series. For example, an important line from Shinichi BOY Part 1 was cut in the anime, but he's powerless against such decisions made by the directors.
Aoyama-sensei has absolutely nothing to do with all the TV-original episodes (also called OVAs or fillers).
#2
The one and only scene in the entire TV series that's drawn by Aoyama-sensei is ShinRan's kiss in Kyoto.
He wrote: "Apply pink to the cheeks, then use a slightly darker pink to draw solid diagonal //// lines. Thank you!"

Aoyama-sensei isn't part of the TV anime team. He doesn't review the storyboards either, except for Episode One: The Great Detective Turned Small (a TV special for the 20th anniversary).
Another exception is the scenes towards the end of The Scarlet School Trip episode, where it shows Ran getting home from the trip and receiving Shinichi's text that confirms their relationship. These were added by Aoyama-sensei.
Keep in mind though, these fixes can be easily turned down by anime directors as Aoyama-sensei doesn't have the absolute say in the anime production. Even manga-original episodes get altered in a way that just don't feel the same anymore when compared to the original.
ShinRan's kiss in Kyoto is especially important to Aoyama-sensei that he offered his original drawing. The blushes are also important to him that he added the comment right beside it. While the anime team didn't mess this one up, they did deliberately remove the blushes from this scene below. Not to mention that they also added a scene where Shinichi yells at Ran.
Can you see why many old fans have been urging people to read the original manga if one truly likes and values Detective Conan? It's the only work that's 100% canon after all.
Below are just my personal thoughts:
I know no anime adaptations are exactly the same as the original, but if you do a one-on-one comparison of a few certain scenes, the intention of the anime team is very clear. It's not like they're trying to hide it. After all, they explicitly said in Haibara Ai Heroine Plan that they wanted to do something to Ran.
Isn't that wild? It's called an anime adaptation for a reason. Its purpose is to retell the original story but with sound and motion. It doesn't have to be 100% the same, but at the very least, it needs to give off the same vibe as the original. Yet, the anime team took it as an opportunity to change it to their liking. To me, that's abuse of power.
It's also lack of work ethics and integrity. Back when Aoyama-sensei just started his manga artist career, the editor didn't just criticize his work but also set his draft on fire!
Can you see the kind of people running the show here? It's outrageous! They constantly twist the original work's canon settings for their own benefits. An anime adaptation filled with the producers' personal preferences is a huge failure to me.
The first half of the anime series is quite alright, but the later it gets, the more filler episodes there are that look like they come straight out of the directors' personal journals. It's their ideal Detective Conan, no longer the original that has been carefully crafted by the author.
What's more is Haibara's voice actress once made a comment saying, "Please erase Mouri Ran." This happened at work and right in front of Ran's voice actress, for crying out loud! And a certain group of people defended her by saying "that's just a dark joke" or "it happened in ancient times." Since when the passage of time makes bullying right and acceptable? And it's not a joke. It's disrespect disguised as one.
If you truly love Detective Conan, please support the original manga. Speaking up DOES make a difference. The impact is small, but if we said nothing, the official side would take our silence as an approval, a weakness, which is exactly what happened in the past ten years or so.
Clearly the anime team is trying to make Conan disloyal just so they can make Haibara the heroine, even after the author explicitly said on multiple occasions that Conan is devoted to Ran. I will never let my kids watch Detective Conan anime because disloyalty is probably going to be the one thing they get out of it.
(This may not be what I think it is, but I admit I had the tinniest satisfaction when reading chapter 1153. That legislator who's reported to have connections with mob affiliates on the news has the exact same name as one of the top producers.)
