I'm not very quick on picking up new shows even when there is quite much hype about it. I guess I'm the kind of guy who likes to stay with his old favorites, and I'm not very persistent viewer of TV-shows (I still haven't seen farther than 6th season of my all time favorite 'The X-Files'). 'Stranger Things' was recommended to my by one of my colleagues who knew my interest in supernatural, 1980s, Stephen King and 'The X-Files'. I have to say I wasn't disappointed after watching the first two episodes and now I'm hooked.
The start is quite slow, but the characters are likeable, the atmosphere and tension are present to keep the viewer interested. The show is taking place in 1980s and it has the nice authentic feel of classic '80s horror movies (that authentic feel is something that most nostalgia driven movies fail to capture), so the shot of nostalgia is another strong reason to give 'Stranger Things' a shot. Wonderful synth score has a lot to do with adding more eeriness to the autumn forests surrounding the small town Hawkins.
Acting is great altogether, but besides Millie Bobby Brown's marvelous portrayal of Eleven, Winona Ryder's outstanding job as Joyce Byers definitely needs mentioning.
After first episode I was hooked and after second, I think, I might be an addict.
