I finished it over the weekend, and thought about putting up a review, but for some reason I was too tired. But if you watch and you really should, you should keep in mind Spielberg's E.T. There are so many similarities to that one particular movie, especially in the set of the time-line and using kids as the protagonist, that it's unbelievable. In a good way.
Stranger Things is a good show. It has believable characters, settings, and consequences that many other show pale next to it. It also has that hook, pulling in the viewers to binge watch from beginning to the end. Only thing, there's only eight episodes and when you see the final minutes, you suddenly which for a couple extra. Or at least making of it interview with the makers.
Netflix did really good move and they continue doing so, by producing a lot of thing from the genre world, and from there gaining viewers from all over the world. If you have read news, normal channel producers are a bit miffed of their success. In fact, they've been dying and losing people to internet so much so that it have alarmed them. I think it's a good thing because the old ways have started producing really stale shows, while Netflix (and very few amazon) is blooming.
So, if you have a chance, check this show out. It's a good one.
