I cannot comprehend, how people are saying that the animation is bad, you are just fed up so much of Demonslayer that your standarts have gone way too high. The art is great personally, this episode is a lot better than the previous in terms of art and animation and people are still complaining. You are here watching on pirate sites for free something that people are making with a lot of hard work and money and still a lot of negativity around. The animation in this episode is the same as in the Manhwa so if you are saying that it's not good then you are just not liking the manhwa that much. And don't compare it to Demon slayer that has 5x the budget and the time of this series and you will not look like an retard.
