I suppose I saw the original “Stephen King’s It” (1990) as it was quite a thing back in the say. But I do not even remember that this appears to have been a mini series. In any case, this remake is also already 7 years old. It was not high on my list.
Muschietti’s version has strong “Stranger Things” (2016-8) vibes. A group of young outsiders team up to fight a supernatural evil. The presence of Finn Wolfhard adds to the similarity.
I suppose you will know the story. A rural American village is terrorized by the clown Pennywise. Children disappear, but it are also children who set out to fight it.
Just a horror. “Stranger Things” is way better, both in the 1980’ies atmosphere and storywise.
