Last year Stranger Things gripped us. A science-fiction inspired story saw a woman find her 12-year-old son missing. She launched an investigation with the local authorities, and as they searched for answers she unravelled some very weird mysteries - including secret government experiments.
The whole thing has led to many conspiracies, including whether it is based on real life events or not?
Some theorists think that the US government had been experimenting on children from the 60s to the 80s. The idea that contact between Eleven and the Demogorgon ripped a hole in a scary parallel universe came from stories that scientists did the same - but with time travel.
She's called Eleven for a start, and not One, so there must be more than one of them right?
Anyway, if series one was good, then series two is lined up to be just as enthralling. The series two trailer, released during the Superbowl, instantly had fans wanting more...
Fan reaction would seem that Halloween is just a little too far away...
Why do I have to wait until Halloween for Stranger Things season 2?

Actor Finn Wolfhard insisted that the new season "will be a lot [darker]. A lot more horror orientated."
He added: "I think people are going to like it more than the first season."
Producer Shawn Levy agreed with Wolfhard's comment, and told Gold Derby: "I think overall the kind of forces of evil that are inherent in season two make that Demogorgon look quaint in retrospect."
It promises to be bigger and better than the last series, and that huge spider thing in the skies looks terrifying.
The show has also brought in two additional directors, Andrew Stanton and Rebecca Thomas, to add to the episodes.
