I honestly am shocked by all the positive reviews and high rotten tomatoes score. Did I see a completely different movie?
IT starts off very well with a genuinely good opening scene. Great cinematography, atmosphere, lighting, a likable child whom you connect with easily, and an interesting encounter takes place between this kid and a very creepy clown. The dialogue is good, there is an eerie sense of dread, and a moment where IT aka Pennywise goes from being a friendly-ish clown to a terrifying villain in an instant through a very well placed awkward stare. It was a moment I wasn't expecting and gave me hope for the rest of the film, then... It's all downhill from there, after an almost laughable use of CG.
This movie has big issues. IT isn't scary. IT's story is weak, if you can even call it a story. IT has too many underdeveloped characters. And IT is a counterproductive villain with no concrete rules for what IT can or can not do.
The overuse of CG ruined any sense of tension or fear and Pennywise's tactics didn't make sense. If he feeds off fear, why reveal himself to each of the kids within a close time period? Why not concentrate on each child individually, causing far more mental torment and making them an easier kill? Pennywise also just randomly manifests himself anywhere at anytime, and disappears randomly. I don't find it scary when the antagonist manifests itself, attacks a character and right before doing damage IT vanishes..
The story is a mess and there are far too many characters. I swear the first 40 minutes is the longest montage in film history. A montage of each child's development and exposure to Pennywise. It was predictable and monotonous. As for the story, I don't know what to say, besides there really isn't one. Character motivations are weak, Bill is the only one who makes sense. Where were the parents at? Not a single parent seemed to care about their missing children. The few on screen parents there were, came off as caricatures. And there were a few scenes that felt completely pointless within context of the story. The school bully and his dad, being the oddest.
So in closing, IT is an uneven movie or more accurately a collection of scenes that don't flow well in a tangible story. There are some good laughs, and a few entertaining scenes. But all in all it's just an average movie. Which should've been an evident sign, when the original attached director Cary Fukunaga jumped ship.
