So Naruto's out of the picture, Bleach is dying a slow, painful death, and One Piece is going to be the last man standing, but eventually out of the picture. So we need a new generation of Big Three. It's gotta be manga which are relatively new, but are heavily gaining in popularity. This means that a manga more than a several years old cannot be part of the new Big Three (sorry Fairy Tail, I love you, but no dice). It could be that the manga is overrated to some folk, but to Big Three, overrated is excluded in a decision.
So I'm gonna post mine, and you are welcome to add to the vote or add your own additions to your Big Three.
1. Boku No Hero Academia (New, massively gaining in popularity, several ten thousand copies sold, retains Shounin formula)
2. Attack on Titan (Touching the age limit, but I think it still holds. Massively popular, several hundred thousand people waiting for Season 3 of anime to come out, has not reached even 80 chapters yet.
3. Akame Ga Kill (5 years old, 11 volumes have sold more than a million copies, just touching 61 manga chapters). I haven't read this manga yet, but I can tell when a large fan base is actively contributing to the traffic rank of manga-hosting websites.
Alrighty! Post your thoughts on Big Three and let me know how mine are.
For starters the term Big 3 was specifically created for Bleach, Naruto and OP. Every generation has series that will stick out, but this can be one, two, three, four or even more. You're forcing it by saying it has to be three. The original Big Three were called like that because they were with three and not that they wanted to have three.
Secondly the term applied to Shonen Jump series.
Thirdly you make it sound that OP is just the last one standing, but that it's practically over. OP is still going to last quite a long time and it has yet to reach the grand climax(es). I do agree though that it should not be counted as even if it's far from finished, it's from another generation. By now a new generation of mangaka has appeared that got influenced by people like Oda. It's pointless to take series into account that belong to the previous generation as then you're bypassing the point of this topic. So series like HxH, Fairy Tail, One Piece by default fall out of the boat.
Anyway you pretty much can scratch both Akame Ga Kill and Attack on Titan from your list. Not because of subjective opinions about it being a good or bad series, but more or less objective reasons that are inherent to them. AoT is a monthly series and I'm not really sure about AgK, but I do know it's extremely slow in release. I once read the series like two years ago or something and since then it barely had any new chapters. Both of them also seemed to have received, and that certainly counts for AoT, their popularity injected by an anime adaption. Before AoT was turned into an anime, it was barely known, but then suddenly it was all over the place when the anime aired. On top of that they are too bloody, too dark to be considered for this position.
I think I can best compare them to series like Death Note and Fullmetal Alchemist. These were extremely popular, but still no one rarely placed these amongst the likes of the Big 3. If the Big 3 are the winners of the 100m, then they are like the winners of the 200 or 400m. It means they're good, but still less prestigious than the 100m runners.
I do agree though on Boku no Hero Academia just because it follows the successful Shonen formula. It's similar to OP, Naruto and with extension to DB. AoT and AgK are completely void of any similarities with these series. Their stories are also too psychological.
Boku no Hero Academia is also a clear example of this generation switch:
Akira (Dragonball) > Oda (One Piece) > Kouhei (Boku no Hero Academia)
Each mangaka grew up with and got strongly inspired by the previous mangaka and their series.
Outside that I would like to throw out Nanatsu no Taizai, though I'm not really in favor myself of that. When I started reading it, it had around 50 chapters and at that point it was gaining popularity. Currently however it's on a point that I got the impression it's stagnating in the sense that it really doesn't look like it will reach the same level of the Big 3. For that its popularity should get a sudden boost.
Another series that I noticed that seems to be becoming more and more accepted by the people, is Shokugeki no Soma, also a favorite series of mine. The issue however here is whether a manga that's purely based on cooking has the inherent potential for that. In the end all the big series are strongly supernatural or fantasy based.
Uhh. Big 3 is only for Shounen Jump..
It's Boku no Hero, AssClass, ???
They are currently the two new most popular manga.
I'm pretty sure Assassination Classroom is nearing its end, so it's rather redundant counting it in.
