- Awesome Music:
- The first opening theme, "Eien to Iu Basho" (Lyrics here).
- Kenji Kawai composed this show's soundtrack. Yes, you did read that correctly. Among the best include "The World of ComNet", "Yui's Theme", "Let's Go with High Spirits!", "Corrector Initialize!", "Comnet Fairy", "Sunshine Girl", and "Unlost Feelings". If you're looking for something that sounds more like Higurashi: When They Cry, this show also has "Grosser's Ambition", Grosser's Fierce Attack", "In the Grasp of Evil Hands", and "A Pinch It Is!".
- Also, the first ending theme, "Mirai" (Lyrics here), is just addicting to hear.
- Fan-Preferred Couple: Fans seem to like Yui and Synchro as a couple thanks perhaps to the Ship Tease that exists between them since earlier episodes of the series.
- Fridge Brilliance: It makes so much sense when you think about it that Mugihito was both Grosser and Inukai's voice actor in the series. Inukai built Grosser as his own image to dictate some authority as ComNet's host computer. The fact that he couldn't escape from him, is because Grosser was built to act and think as himself. Then, Inukai took advantage of saving his memory with the intention that Grosser wouldn't find him so easily, because he goes amnesiac for a while. This also explains why he couldn't find the correctors by his own account (since Inukai ordered them to hide), and why he tricked Haruna taking his creator's image.
- Fridge Logic: How does the ComNet work? How is it possible that a person's conscience can get trapped inside a global network of computers, remain asleep in the real world, and have everything that happens to you there affect your physical body in a world where Wireless didn't seem to exist? Maybe Magic, Maybe Mundane?
- Growing the Beard: The first season was good, but the second was a improvement for those who didn't like the first.
- Hilarious in Hindsight: José Luis Reza, Control's Latinamerican dub actor, ended up being casted as Captain Harlock in three different Captain Harlock properties: Gun Frontier, Cosmo Warrior Zero, and the 2013 CGI anime movie. Control's first appearance in the anime series was under his "Captain Shadowcat" alterego, an expy of Harlock.
- Ho Yay: Played for Laughs in Yui's Comic Strip Theater from Episode 4. Yui asks Shun if he has a girlfriend, only for him to deny it by saying he has a boyfriend, shortly before announcing he was a girl all along. There's also an episode in the second season where Follow proposed to I.R. while dressed like a Bishōnen; In his case, I.R. didn't protest much and just blushed before the reveal.
- Les Yay:
- Rescue's affection towards Freeze could be seen as a romantic attraction, and it doesn't help that Freeze acts as a tsundere when she is present.
- Yui and Ai. As long as the second season goes up, it's clear the intention of defrosting Ai Shinozaki with help of her neighbor and eventual friend, Yui. They are opposite poles, and while Yui tries so hard in seeing Ai as a friend since their schools' Drama Club co-joint, their scenes together fuel the shiptease (especially this afforementioned episode, where the drama they perform also plays with the idea).
- Nightmare Fuel: Shortly after Kurokawa finds out that he is dead in the real world... the Boggles transforms him into a monster. It's a gruesome image, not only for the visuals but because it shows (and you can listen to it, as well) its painful transformation.
- Retroactive Recognition:
- Hiroshi Kamiya as Takashi. Especially since his popularity started to peak since 2006. He is not particularly desperate to be noticed, though.
- Makiko Ohmoto is well more known these days as the voice of Kirby since the first Super Smash Bros. was released. As a play of hilarious hindsight (or it can be harsher, too), Yui became the ultimate pop sensation idol outside of a silly VR fantasy!
- Tear Jerker: The final episode is basically a happy example of this for Yui.
- They Copied It, So It Sucks!: Back in the day, it was accused of being a cheap knockoff of Cardcaptor Sakura.
YMMV / Corrector Yui
