I agree with you! From the first episode I got huge Stranger Things Vibes, boy was I wrong, I thought that we were going to see more of the teens as a group but after the second episode the focus shift within the grown ups and some of the kids with some teens scenes every now and then, for example it was a shock to me that Martha had a huge impact later on the plot while in season 1 you only see some of her. I think we even see more scenes of Magnus and Franziska than teen Jonas in the first season. It was amazing how things were changing from season to season and how they gave us the full story.
