I don't know if the previous reviewer has read the actual first chapter or not, but I am sincerely interested in reading more. imo, the story is much more interesting than the typical tournament/powerup shounen series.

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.

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.

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.

Interesting manga to say the least and scores high points on originality, comedy and execution. Certainly not your typical shounen manga, and manages to score lots of laughs whilst still being well grounded.

A lot of comments have criticized the manga for simply having too silly of a storyline, but honestly the manga more than compensates with its clear cut direction and intent. Each page is sharp and witty (more than I can say for a handful of other shounens), and despite the quirky plot the flow of the manga feels surprisingly natural.

If you enjoy a good laugh and are looking for a manga that doesn't have a thousand cliche's packed into every panel, then you won't regret taking a look at this title.

I, for once, think the idea is cool. Well, you can use other words such as creative, original, amusing, remarkable, but to sum it all up, cool fits perfectly. Since I sincerely like the mangaka's other manga (Neuro), I have rather high hope for this one. That is with proof that the flow of the story so far is really interesting. It gets more gripping chapters to chapters.

As for the comment below me by Ninetails-Naruto, please, this story is more than enough worthy of being serialized in Jump, much better than some current popular series that bored one to the utmost extend.

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

Matsui Yusei shows that he's a consistently entertaining writer. If you haven't checked out Neuro by now, well... you probably damn well should! Anyone who tries to denounce a strange premise solely on the basis of being strange knows jack shit. (Looking at you Ninetails-Naruto) An author can pretty much sell anything so long as the writing is good enough, and in this case it is.

Anyway you've probably never seen something like this before, so give it a shot.

I gotta say, starting out I loved this manga. It was interesting, unique and had a funny but serious tone on the school life/slice of life genre. However, honestly after so many chapters just like naruto, bleach, one piece, fairy tail, and ALL OTHER shounen manga, I eventually dropped it. It just became way to repetitive and dull. Also the story arc that's taking place now should have taken place a LONG time ago.

In the end I'd say if you don't mind a common but unique twist on a modern day shounen manga then be ready for a wacky, crazy, sometimes sad, sometimes serious story with the right balance of action and drama to keep you excited for a while.

A nice touch of originality on the school life norm with the koro-sensei-going-to-"destroy-the-earth"-issue and whatnot. Really enjoyed the characters since they're all so unique and different. It is a little cliché sometimes with the flashbacks and the like, but there is enough plot to keep you hanging on without a sudden overload of events and plotwists.
