These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Mahou Sensei Negima
Alternate Character Interpretation: Konoka acts like a Genius Ditz at first glance, but her excellent academic record, too-flirty-to-be-totally-innocent remarks to Setsuna and masterful handling of berserk Tsundere Anya point to Obfuscating Stupidity. The fact that we've only directly seen her thoughts twice (both for minor things) in the entire series helps.
Any new pactio formed has a good chance of being exactly what the gang needs at that very instant.
This is averted and lampshaded in an episode of Negima!?. Haruna, who had just gotten her pactio, says "Hey, maybe my power will help!" Negi spends about a minute activating the pactio... and Haruna's power is that what she draws comes to life, which is not at all useful in the situation.
Later, Negi demonstrates a spell specifically designed to find the right partner for a given task.
It's especially bad with Asakura, since she was one of the first ones to learn about magic, but didn't make a contract until right when her artifact was needed (over a hundred chapters later).
The fandom does not appear to mind Jack Rakan's self-aggrandizing statements about his power and abilities (To quote him, "I have no weaknesses!") - probably because he more or less lives up to his claims, and then some.
The Anime Final movie also seems to be causing this, for similar yet different reasons.
Broken Base: The ending of the series. Most fans found it left too many plot holes hanging, was too rushed, and wasn't satisfying.
Complaining about Shows You Don't Watch: The series has a lot of people who believe that the series is nothing more than a Shotacon Love Hina with magic. Although it takes a bit of time to do so, the series does get quite Shoneny for later chapters, though the Harem feel is prevalent throughout the work.
Makie topped the first two character polls despite not having done much of anything.
Eva is quite possibly designed for this: She doesn't appear very much, but when she does she tends to dominate the scene.
According to Word Of God, Madoka's involvement in Ako's first Day in the Limelight arc boosted her popularity, and we should expect to see more of her in the future.
Fan Dumb: "How dare Zazie oppose Negi and show him what CE is about! Whore, bitch, slut, skank! Let's brand her as a Complete Monster before she even has a chance to explain herself! ... Oh wait. Sorry, Zazie".
The upcoming series finale seems to be causing this as well, with some outraged fans wishing (hopefully not seriously) death upon the author. While there may be reason to be disappointed, its gotten a bit extreme.
Foe Yay: Anything involving Asuna and Ayaka. They seem to be more of friends and rivals.
It doesn't help that in the next chapter Negi conquered his inner demon by deciding to befriend Fate!Here we go again...
And now in chapter 311, it turns out that Fate isn't the only averruncus, there's actually 4 of them and one of which is FEMALE!!
"Funny Aneurysm" Moment: As part of Negi's and Kotaro's training in a diorama for their match against their mentor Jack Rakan, they do press-ups with huge rocks engraved "Defeat Rakan-san" on their backs. Later, they return to the diorama after Fate defeated and erased Rakan from existence to discuss strategy; the rock isstill there.
During Tsukuyomi's first appearance, she mentioned wanting to make Setsuna and Konoka hers. That comes off a lot differently now given... what we know now.
There's also some between Setsuna and Asuna, especially when Asuna starts stroking Setsuna's wings.
And now in chapter 336, Fate has joined the fray. (Then again, this isNegi, so it's quite understandble.) And even before this there had been some implications of Foe Yay.
Negi makes out with a Robot Girl so hard he gives her a soul.
A running gag throughout the series is Negi's tendency to try and encourage people through speeches that are all too easily interpreted as romantic propositions, which Chisame lampshades as his "Natural Gigolo Talk."
Moe Moe: The series in general, especially in regards to the female characters.
Moral Event Horizon: Fate pretty much flies over it when he tries to KILL Negi with a stone spear through the back. And Tsukuyomi does the same thing when she tries to rape Setsuna.
Narm Charm: The official English translation of the Manga, specifically Ku Fei's semi-Hulk Speak dialect. It's a spotty means of translating her tendency to stick '-aru' where it shouldn't be, but it grows on you after a while.
No one is ever, ever going to forget Chachamaru's winding incident. Probably 'cause they just keep happening.
There's also Chachamaru getting chopped in half. It's become a sort of mini Meme in certain parts of the net to photoshop various reasons for her to be cut in half, like a Rider Kickfor instance◊.
Too Cool to Live: In chapter 278, Rakan finally succumbs to the might of the Code of the Lifemaker and disappears in front of Negi. Then he comes back from the grave (briefly) to Bright Slap Negi out of his unstoppable rage. It just takes spirit.
Villain Decay: Notably subverted and twisted with Evangeline: although after her first defeat, she is no longer really an enemy, she later reveals (several times) that she is far, far, far more powerful than she let on at first, making her absolutely terrifying. Among other things, she uses her ice magic to shatter a demon several hundred meters tall, she KOs an extremely skilled martial artist in one hit without her magic while she was distracted by thoughts of Negi's father, and draws a character into an alternate dimension (well, an illusion of it anyways) and proceeds to nuke said character multiple times. Motive Decay? Maybe. Villain Decay? Not even a little bit.
Is it even Motive Decay? Did she really HAVE a motive, excluding getting out of the Academy, prior to her fight with Negi?
It's too soon to decide she's a good guy now. She may simply be watching the show and consider it "unrefined" to interfere at this stage, as with the World Tree arc. She's said several times that the characters shouldn't get too close to her, and in a bit of possible foreshadowing, that she should be thought of as the "last boss" in a video game.
Akamatsu has a habit of bringing villains back; remember when Fate was just a powerful side kick?
Being a happy little boy with an Unwanted Harem of hot cuties aside, Negi has been through enough pain, horror, and trauma in his short life to give the most hardened Child Welfare officer nightmares for months.
