Don't be misled by the fact that the main characters in the series are children. All of the main characters are very good actors and play their characters very well. The friendship between them is the kind that everyone would want. The story of the series is also kind of immersive. Secret experiments, people with special powers, other dimensions... It is one of the series that makes the best use of special effects. I said child actors are in the lead role, but that doesn't give the show a childish feel. In fact, the series adopts an extremely dark theme. It also describes this dark theme in the best way. If you want to watch a series where the science fiction is well done, the effects are good and the story is good, Stranger Things is for you.
