The Duffer brothers took all the best aspects of the first 3 seasons and made them better in the latest season. The practical effects were amazing which was expected considering the massive budget, all the new characters are intriguing. I just wish the Mike/Will/Jonathan/Argyle storyline was given more screen time but I'm sure they'll play a larger role in vol. 2. Overall this season was spectacular and well worth the 3 year wait.
