Just my opinion, of course, but I think Stranger Thing is overrated. I've watched both seasons and thought it was okay, but nothing special. My favourite thing about the series, and the reason I've watched every episode, is the nostalgia factor. I was about the same age in the early-to-mid-80s and I love the look and feel of the era.
My teenagers think Stranger Things is top shelf, and the general feedback is overwhelmingly positive, so I'm filing this one in the "not my cup of tea" drawer. It's not you, it's me. To be honest, I found the whole upside down world boring.
The kids are cute, though... and the opening title sequence and theme is perfect.
