I love the book when I was a Teenager. So i was very sceptical in the beginning. But the 90ies vibe and the goonies-style got me from the first Episode. The german actors are really good and the character developement is interesting. A good example is the mother even when she is just a small sidekick. But the casting could be more diverse. The lenght is with 6 Episode perfect. I had a too much chewing gum story line feeling with a lot of other series but not gryphon . I hope the series will continue with an second season. It would be interesting what the write of the book is saying about the series.
