This is a wonderful show exploring a single mother (recently widowed) coping with her effort to make a living while centering on her very special son.
The adults have very adult interpersonal and professional problems, on top of the supernatural disaster that started in Iceland, but threatens Dion, his mom, and their struggle to live a normal life.
Dion is a goofy kid, not always the master of his impulses. This is the source of some comedy and also some very serious drama.
I think if you give this series a try, you won't be sorry.
