What especially impressed me was the uniformly excellent acting of the children - really very impressive.

I always think "tone" is one of the most important qualities a movie needs to possess - it needs to be coherent, well-thought out & consistent. "Stranger Things" has a very particular tone - the '80's feel, the homage to horror/sci fi/fantasy traditions - that is perfectly realized. It manages to be referential & "cliched" while still seeming fresh & original - a very clever trick. Congratulations to the Duffer Brothers!
