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.
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.
