The girl 11 gets her superpowers hard way. She has very few friends each friends have been given a perfect character arch and by the time you reach season 4 you kinda know how they ll react to certain situations. Third and fourth season as all characters enter to their adulthood few more chuckly scenes , few adolescent crisis but that is not what stranger thing is about. It's about watching supernatural story and trying to find out the normal people bravery to save the world. It's about alternate dimension and nerdy explanations given by nerd kids .it's about what if the childhood game is portrayed as the reality in a series . An interesting series to (binge) watch . Till fourth season it won't disappoint you if you like first season. Go for the unique ride.
