Well, since yesterday i finally updated Samurai 8 (only had read the first chapter), now i'm up with all 4 mangas and well, i don't really get much of the criticism from some people here, i like 4 of them, to me this is the best serialization round in a good time.
Samurai 8 is perfectly fine, the art is good, the characters are nice, Kishimoto is taking his time to explain everything since he isn't in any danger for pretty much a year but at the same time isn't as slow as Saiyuki, and being totally honest, i find all the criticisn from some people a bit forced, it seems some people just want to hate this so much that they find any excuse to do, i don't care if it's a bit slow, Kishi is obviously taking the "long term" journey and i'm okay with it.
Futari no Taisei it's one of the most refreshing sports manga that i ever read on Jump, of course isn't perfect and anything, but it's seriously interesting and i don't know what it's so "confusing" about it based in some people's comment about how much of a "mess" the manga is, but i get that it's a bit hard to see where the story will go, but for now i'm enjoying the characters and the "Tai and Sei" thing.
Beast Children is pretty much the "by the book" sport manga but at the same time it has some charm and also heart, isn't bad is just "typical" but it will not be any surprise if it flops but i think it's getting better each chapter.
Tokyo Shinobi Squad it's the surprise to me, didn't expected anything and the manga became my favorite with Samurai 8, yeah isn't like the most original stuff in the magazine but i really like the art and the main characters, specially Jin, overall the manga it's a really cool read.
Not really trying to start a whole discussion (that will probably become a mess), just putting my thoughts about the new mangas since everybody do the same, things will get ugly since i like Kamio Yui and even Saiyuki too, but it's how things work in Jump...
