The plot, although a fantasy one, was solid enough.
The characters didn't waste time with self-evident and totally obvious things. The idea was that the characters had a problem and they should solve it. The show didn't use 90% of the episodes on stupid misunderstandings, boring flashbacks and totally unrealistic twists. For a fantasy plot, it was sensible and also it had some good ideas and twists. It wasn't lazy writing, just too basic.
The acting was not life-changing, but it wasn't bad either.
