This would be a suggestion for Tweens and older. I do like this series on Netflix. It reminds me of some of the classic 80s movies that Spielberg created including Goonies and Poltergeist. The creators of the series master the rising climax effect that Spielberg meticulously mastered back in the day.
Another aspect I like about this series is the importance of adventure for tweens and teenagers. Science fiction allows us to imagine a world as adults that tweens imagine every day. The exploration of life beyond our limited world. A world of comic books, and sci fi thrillers allows for imagination to develop. A world that play can lead to dramatic outcomes.
The series is for older kids and adults. I still recommend viewing it with your kids. So many references to a time that has past, that might inspire a trip to the grave yard or moonlight walk. The idea of mystery is a great aspect to the world we live in. Too often, technology replaces the realm of imagination, and the places it can take us.
