Having no previous experience with It in any form, I had no real expectations for this. It was okay, but the scare moments are way heavy handed. Subtlety would've been more affecting. This reminded me a lot of the recent Annabelle Creation in terms of how scares are delivered. Loud sounds, screeching violins, more loud sounds. Really obvious and it might work on a lot of audiences, but for me it leaves no lasting impact. And really, that's what I come to horror films for nowadays.
My favorite shot of the film was from the scene in the library wherein one of the kids was researching Derry's history. While the shot focuses on the kid intensely flipping through the pages, you can vaguely see in the blurred background one of the librarians staring and smiling at him. The background is blurred due to depth of field so you can't really see her in detail, but it's unmistakeable that she is staring right at the kid, and he's completely unaware. It's a deeply unsettling shot because it never calls attention to her. No cuts to her, no rack focus shift. It's only noticeable if you are really looking for it.
I wish there were more bits like that, because I otherwise I really don't think the film left any mark on me. Great kids though. Very likable and convincing performances. I liked them all. Best thing about It, really.
