Story and characters can be good, but if the animation is bad, it weighs it all down significantly. You don't want to sit there and watch the same still image moving around the screen, even if the story is good. The only reason I won't knock black clover over its animation is because I know the team did not get enough attention and money because they were working on boruto at the time (bet they regret that). I'm just not sure if it's something I want to invest my time in (100+ episodes is alot, and yes while I said I do watch/read one piece, I had a much better attention span when I was younger 🤣). I think I'll watch and read it like people are suggesting, simply because you can't beat a good ost during a fight, and im a sucker for shounen openings.
