The creature will teach class 3-E how to assassinate him before the year is over.

I started reading Assassination Classroom almost a year ago, when it only had 50-70 chapters or less. It was really good and funny. The balance between comedy and action was there, and though it was running on a dangerously thin line between the two, it stood to be really good. Well, to me, it was, until the manga took so many different turns, it became rather painful to read in the end.

Spoiler (mouse over to view)
Firstly was when Itona (the one with tentacles) came in, and the random mask guy.How they bought over some guy, and shit happened. That part was fine, but when I'm re-reading it, I always skip that part, because, seriously? You added a random masked guy which nearly killed the entire class to kill Korosensei? No less, he's Kayano's (that's not even her real name, wth?!) BROTHER?! Like dude, that's overdone. I mean, I can imagine why, since the brother has the tentacles cuz his sister was working in a research facility which Kayano picked up, but seriously? Plus their sister was the one who Koro-sensei most likely fell in love with, thus becoming a teacher? (And, why the heck would he leave a note for Kayano to take revenge. A little...titbit you don't really do unless you're asking for your death.

And then I come to the part of Kayano. I really started dragging my feet on reading the updates when Kayano wanted to kill Korosensei. Some people may like it, but I don't really fancy it. She's actually the best assassin in the entire class due to the tentacles, instead of Nagisa? (I root for Nagisa for being the best assassin, truth be told) For me the manga really took a turn for the worst in that arc. Plus, Nagisa kissing her. (Ouch. I'm a KarmaXNagisa fan) I don't know why, but this manga has the tendency for making the weakest characters becoming the best assassins...

I'm seriously wondering if I should take this off my favourite manga list. I suppose I'll have to wait to see the new chapters before I can decide...though this was a really engaging read at first, the process was rather...weak, in the end. Like they did it for the sake of doing it. I'm quite disappointed with the manga now, for the random (and I feel rather unneeded) turn of events.

Well, this is my personal opinion of the manga. It's a good one, but I'm thinking of removing it from my lists...others may beg to differ about this manga being good throughout, but for me, nah.

Dangerously Cheesy

The concept of an alien instructing a classroom full of kids on assassination is refreshingly original, as mentioned by pretty much every comment before mine. However, while the classroom is as wacko as I'd hoped for, the atmosphere gets annoyingly serious sometimes with oh-so-tragic pasts and life-lessons. Since pretty much everything else about the manga is so over-the-top, it really makes the shift in tone come off as cheap and cheesy instead of emotional and heartening. I know it eventually has to become more emotional and plot-driven because they'll be killing their beloved sensei, but the way it's handled right now is really awkward.

It's interesting though, and, depending on how the ending plays out, could really shine. Definitely worth a look.

One of the best manga I've read so far... comparable with fullmetal alchemist, gintama, lucifer and biscuit hammer (hoshi no samidare). The plot is original and developed really well. All characters have strong personal trait and no one is dumb enough to become side dish figure. The art blend really well with the theme of the story... Overall, still flawless so far (with standard of error 5%) in my opinion of course. Thanks for the genius author...

I first thought this was going to be a very weird series, and it is, but it really has some depth to it. It really is worth reading. One thing I'm still confused about, is why the whole class is so prideful about wanting to kill their teacher. Sure saving the world and getting a reward is one thing, but they talk about killing their teacher themselves like it is the most innocent thing in the world. I just don't get it.

Why is this marked Tragedy? I mean, I know something happened in Koro sensei's past, but is it because of that? Or is something going to happen after they kill him? Anyway, I really love this, Matsui Yusei is a genius for making it. And I can't wait for the anime adaption! smile

What's up with all those mediocre reviews? What do they expect of a manga with such a story description? Something really deep and moving? Sorry, you should move on. This is a shounen series after all...

What you see here is a perfectly well made gag manga that has a quite slow moving plot. For now read it for the comedy, later on for the actual plot. It will become more serious at some point if my prediction is right.

It is basically Great Teacher Onizuka on acid. Reminds me somewhat of Sayonara Zetsubou-Sensei in that regard.

Sure the premise is retarded, but ridiculous premises that somehow make great stories is why I read manga

Deeper than what it seems

Assassination Classroom is an excellent manga. I've noticed that its getting good to mediocre reviews due to the whole plot and details, but this manga goes much deeper than the ordinary assassination plots and school life. Assassination Classroom is not only about a bunch of low-ranking students on a mission to kill their teacher before graduation, but also how they learn to work together and explore the weaknesses of their target and teacher with each passing chapter. This manga shows the true nature and relationship of assassin and target, teacher and student. The humor inserted in this story helps keeps things interesting and gives it more of the school-life touch. Assassination Classroom grows and develops, and it will also grow on you.

Yet, it somehow doesn't seem as funny as it should be. It's quite amusing but not laugh out loud funny, which was what i was expecting from the premise.
It kinda sucks how education makes me a little ticked off when the impossible happens in manga/anime bigrazz (or, rather, the impossible happening with no explanation e.g. there being no catastrophic effects from the moon being mostly destroyed) but it's something I've just got to get used to personally and I suppose it has no place in this comment... <,<

I was kinda surprised by the tentacle rape being used as a joke in WSJ but...*shrugs* Japan, man. bigrazz

The series in itself is fun, I'm a big fan of Matsui Yuusei's extremely weird humor (though this is not his best work by far) BUT in my opinion, the plot, though not uninteresting, can't work.

The students are obviously fond of their alien teacher and vice versa. In this situation, anyone who's not a psychopath nor a complete retard will realize that there is no way he's gonna kill the target, weird alien or not.
So there is a feeling of pretence in the story. Every time the students make a move of the teacher, I get the impression that they're pretending, since the atmosphere makes it impossible in my mind that they'll actually go all the way...

On the other hand, depending on how the story unfolds and how the atmosphere evolves (I've only read 4 chapters so far) this paradox could lead to very interesting psychological situations and dilemmas. *_*
So, let's wait and see
