The reviews are negative because most people expected a blockbuster series with Nicholas Cage.
While this series has none of those above, it is worth the attention! It features new, young actors (with the exception of the formidable Catherine Zeta Jones) and the characters are relatable with modern challenges. While the dialogue a bit weak at times, the storyline is original and i binged three episodes in a day.
If you expect a super hollywood cast move on, if your eyes are open to a fresh adventure-hit play and you won’t be disappointed !
edit: just watched the last episode and I am so sad it's over. They don't make wholesome adventure series like this anymore. I hope there's a season 2!
