I bet people who say this anime is great haven't read the manga. I must it that indeed this anime isn't bad IF you don't compare it with the manga. I might even give it a 7-8 score if I only watched the anime.
The manga is hundred times better and this anime just ruined it. It ruined their characters, the story, and many things. I won't talk about the art, sound, etc. What I'm gonna talk about is the comparison between the anime and the manga.
Most of the filler episodes are- how do I put it- shallow maybe? (Idk if I use the right word). Some of them are irrational and silly. They are really different than the episodes that follow the actual story.
The manga has some funny small scenes. Those things actually make the characters more interesting. Too bad the anime didn't include them.
WARNING: The following review contains SPOILERS.
[MINOR SPOILER] I really don't understand why they changed the characters and their backgrounds so much. These are the differences:
-Onogida and Michiru aren't in the manga.
-The actual section nine only has dudes. Well, there's Amachi. She s the section after Aoki.
-Okabe doesn't have a wife in the manga. There’s actually a funny scene where everyone thinks that Okabe has a daughter who almost graduates from college. It turns out he’s only 36 and is still single.
-Aoki can't do lip reading and he doesn't love his sister in the manga. The story about the president is actually something like a spin-off. Thus the characters are different.
-Amachi characters is so annoying in the anime.
-Aoki is also really annoying in the anime.
-Maki's interesting traits don't show in the anime, like how he's feared by his subordinates in a comical way or how pretty and young he looks (fyi he's already in his mid 30s).
-Miyoshi isn't that different but somehow the anime made her look like a secondary character who suddenly makes an appearance just for giving Aoki a love interest when ACTUALLY she's important for Maki and Aoki's character developments.
It feels like the anime just adding more unnecessary characters and plots. All those things make me cringe cuz they're not in the manga and they are overly dramatic, especially the ending. It was so lame.
[HUGE SPOILER, kinda] About episode 20. The anime doesn't describe whom Maki is jealous of. People might think that he's jealous of Aoki for getting together with Miyoshi. The truth is he's jealous of Miyoshi. He's jealous cuz the people he cares for (Suzuki and Aoki) get hooked on Miyoshi.
[HUGE SPOILER] Amachi died in both anime and manga. The difference is the way they animate the arc. In the manga, Aoki regrets the way he treats Amachi when she's still alive. He's kinda rude to her. But in the anime, he regrets that he talks about his father to her and this lead her to falls into a trap. Aoki thinks it's his fault that Amachi died EVEN THO she's the one who asked him about his father. It feels forced and silly smh
[NO SPOILER] Lastly, about the relationship between Maki and Aoki. The manga describes more about them. You can see their bond more clearly!
Actually this is the very reason why I'm disappointed with the anime. The interesting thing about the manga is the relationship between Maki and the people that surround him. I barely see any of those in the anime.
My thought after finishing the anime: I feel like I just watched a fan fiction :/
I actually have more complains but I might as well write an essay lol (I’m pissed at how I write this review more seriously than I’ve ever done my school works).
Tl;dr: JUST READ THE MANGA. You won't understand just by reading my review. Seriously, just read it. BUT if you insist to watch this anime, I recommend you to watch it first before reading the manga so that you can still enjoy it. However if you already read the manga, don't bother watching this. You’ll be disappointed if you expect something like the manga.
