Actually really enjoyed this as a standalone show. I watched this with my nine year old daughter whom also really loved it. Completely binged it and thoroughly enjoyed the suspense of it all. I likened it to the tv series, "Legacies". Lots of non human species, murder mystery, suspense and teen drama.

As for a spin-off of The Addams Family, it isn't really kooky or have the overly morbid humour like the original The Addams Family was. A bit of a letdown with that side of this tv series.

Overall, I actually rate this show and really looking forward to what the next season/s bring to the table.
