I'm so happy!!!! For once, childhood not ruined!
It doesn't take very long to adjust to the animation style. It's actually very beautiful and enhances what you already know that's familiar about each character. Everyone's spirits are captured perfectly. Sven is now Shiro, and is probably the largest departure from the Swedish version, but he was pretty much a blank slate aside from his mystery arc, which I'm only one episode in so far, but there's definitely a mystery/secret involving him.
