I agree that from start to finish it was almost flawless. The only minor flaw was that...

Spoiler:

Winona Ryder made it back from the Shadow Realm, it would have been more satisfying if she had been trapped there forever. There's always future seasons I guess...

In all seriousness though, one of the best shows I've seen in a long time, maybe ever. It captures the tone it's going for perfectly.
