I don’t know how you walked away from The Shape of Water with such a shallow reading, but eh, not everyone’s taste in films is the same.
I have a great dislike for the sorts of horror films where horror is conveyed entirely by long drawn out tension into a jumpscare. It bores me and then I stop caring about what’s going on in the film. The Woman in Black is one that immediately springs to my mind, ironically because of how bland I thought it was. It’s what you’d get if you told chatGPT to write the script for a horror movie. Just a bloke stumbling 'round a house at night being scared by random shit punctuated by daytime exposition scenes. I know it was trying to trying to say something about grief but I just couldn’t care enough about it after the spooky violin lead up to the protagonist being startled by a tap making a loud noise when he turned it on.
