Not original at all, all the plot lines are re used from previous seasons. It relies way too heavily on nostalgia instead of actual plot. It's just as if Netflix thought : "what's a good way to make money?" And they just compiled a list of things they thought people would like and squeezed it into a show. An important part of a show is theme and pacing. I actually really liked season 1, but by season 3, it doesn't feel like the same show. All of the characters are one sided, the dialogue isn't believable, and the theme and colour palette completely changed. They drop plot lines left and right to the extent when the show is just straight up confusing, and not in an interesting way. Winona Ryder, Millie Bobby Brown, and Noah Schnapp are all amazing, but the writing is predictable and boring. There just isn't anything special about Stranger Things. It isn't unique or interesting. Don't waste your time on it! Lots of shows are set in the 80s that aren't just a jumble of overused tropes. If you are looking for a sci-fi show that involves missing children, watch Dark on Netflix. The writing is incredible and the actors are phenomenal!
