Everything that this film needed to live up to the mini-series it did. Bill Skarsgård as Pennywise was not just downright terrifying there was nothing funny about him at all. but also creepy and felt sociopathic and inhuman. The chemistry between "The Losers Club" made this movie. From the opening scene, you feel it and connect with the characters.Everything about them felt believable the way they acted and spoke felt like the way you acted and spoke whenever you were kids and adults weren't around. The interactions between Finn Wolfhard and Jack Dylan Grazer were hilarious. Their back and forth one-liners bring a layer to their chemistry that almost steals the film. Sophia Lillis also stands out. Her ability to emote and draw you into the scenes of terror that don't even involve Pennywise provides some of the horrific scenes of the film. Andy Muschietti produced some of the best jump-scares I've ever seen on film. The way he used the score to give the film momentum and rise into and enhance the scares was masterful.
I absolutely loved this film and I'm not a huge horror fan. Bill Skarsgård joins Tim Curry and Robert Englund in the pantheon of horror villains. The film definitely has Stranger Things vibes with standout performances of the children of "The Losers Club." Yet the film doesn't shy away from violence towards kids and that gives the film stakes. The pace of the film balances the moments of terror and humor. The film crescendos and exactly the right moment and feels not a minute too long. This is a movie to watch in a theatre with a crowd and one of the best book to film adaptations ever made.
