So far we have received 3 out of 5 seasons for stranger things and my god are they incredible, the first season is a horror mystery revolving around a young Will Byers going missing, simple superb, each character has they're defining moment and each played a major part in the series plot, Season 2 was equally as charming and brilliant, add new characters such as Billy, Max and Bob, all 3 of which being incredible additions to the already phenomenal cast. Apart from the less than underwhelming Episode 7, season 2 was just as brilliant as season 1. Season 3 was much darker and grittier but with a lot more comedic elements giving it an exceptional blend between intense action, charming character moments and comedy. Overall Netflix has created one of the best TV shows of this century, Bravo Duffer Brothers!
