Does Demon Slayer's animation outweigh its other aspects, such as storytelling, in terms of quality and appeal?

I enjoyed watching Demon Slayer, which had great voice actors, characters and top-tier animation. However, I've been wondering if the storyline is average, as I've noticed people often criticizing the series, leaving me to ponder whether the storylines are actually good or not. If it had one piece level (im sorry) animation would it be as famous as it is now?
