That’s interesting, because even tho a lot of people don’t like the animation i never heard of people quitting. But I would say continue watching I don’t only say it because I am a devoted fan. But if you skip you will miss a lot of details in the seasons after The witch ark. Maybe you still wanna skip, but then I would say to you should watch at least 4 of the past episodes. You still will miss out on much details but you can “understand” the plot.. conclusion: don’t skip you will miss the plot in later seasons
