Dude wtf are you babbling about? I was talking about some user saying OP is popular therefore it must have good quality. I seriously have no idea what you're going on about.
If you are going to call argument of popularity a fallacy, don't rely on "common sense", because common sense itself is an appeal to popular opinion and common sense differs on a variety of topics throughout the world, by no means a universal truth.
If you call something "bad" then you need to qualify what it is "bad" at.
Is it "bad":
at telling the story of a war on multiple fronts
letting us know how the fights are progressing
what inventive methods and powers the characters use to fight
and what road blocks characters are facing?
selling manga volumes (argument to popularity, but also a metric)
No.
Is it "bad" at:
looking like a One Punch Man double page spread, drawn by one of the most skillful artists at that style
(with no dialogue or background)
(or inventive powers)
(that take an age to draw and are not appropriate for a weekly series)
(that are based on a pre-existing storyboard in the form of the original webcomic.)
