I would argue it's still an unfair generalization and broad stroke to paint, even if we're limiting it to Battle Shounen. There are and have always been good ones and bad ones just like any other genre (or sub-genre in this case).
Well okay if you think I'm still drawing too much of a broad stroke here, I'll gladly narrow it down even further:
Shonen Jump.
If that's still too much of a blanket generalization for you then:
Then the Battle Shonen series of WSJ.
Or in the words of SSJ3 Goku, I'll "go even further beyond":
The most currently mainstream ongoing battle shonen series of WSJ.
Either way: You can't honestly tell me that current anime/manga have been constantly spammed and flooded by battle shonenshit the most for years especially here in the West.
And that at least half of battle shonenshit series that are popular right now are all derived from Shonen Jump.
And the fact that it's all I see here and they're practically the only thing everyone talks about, is primarily what keeps driving me away from anime/manga and pushing me towards the side of american comic characters, western animation, and even much of american/western media all too often.
Like I acknowledge there's some stinkers and that two of the three HST series (Naruto and Bleach) turned to shit by the end, with several modern ones actually topping them in terms of downfall (which is really saying something).
Really? But I guess the only anime/manga series that can potentially top the HST's downfall mainly being other modern battle shonenslop series kinda makes sense.
There are still good ones though, there're just less of them than there used to be.
And this is precisely what I've been meaning to say all this time.
