Let me expand on what I'm talking about. The book, for all its flaws, lets you into the Torrance family. Jack's messed up, but he's doing the best he can. Wendy is much stronger a person in the novel than in the film. And Danny is quite a charming and intelligent little kid.
Not so the film. In the film Jack's a vacant parent, a vacant writer (we have no idea what kind of writer he is in the film - for all we know 'All work and no play..." might be the best thing he's ever written), and a vacant husband. No offense to Shelley Duvall, but they couldn't have picked a worse actress to play her. Sure, maybe the intent is to say "No wonder Jack went apeshit, look what he married," but again, if Jack is supposed to be a normal guy before the hotel got him, he would have never married... that. And Danny is a sympathetic character until he turns into Twitchy Finger Kid.
Maybe I'm reading too much into these characters and Kubrick was trying to create archetypes of the broken American family. But I need someone to care about in a film like this, or it's all meaningless. You can say that that's not what Kubrick does, but I don't agree. In a weird way, Kubrick summons sympathy for Alex DeLarge. He may be laughing as the world burns in STRANGELOVE, but I think there's also some sympathy there too. I definitely cared about Pyle in FULL METAL JACKET, and even Joker too. And for me, I need more than just an archetype in horror. I need to have someone I'm willing to journey with when the shit goes down or I'm just watching terrible things happen to someone I could care less about.
In UNITED 93, with just a few brief strokes Greengrass gives you a multitude of characters that you're willing to go to the rack for. I bring up Greengrass here because I very much felt while I was watching it that Kubrick would have very much appreciated UNITED 93, its streamlined mode of storytelling, the clipping of all the bullshit that surrounds movies like that. And Greengrass makes completely sympathetic characters here with very little dialogue and screentime. We have a long time with Jack, and when all the shit goes down at the end of the film, I'm not watching anything that engages me on more than a technical level, because I've long stopped caring about who I'm watching.
There's a lot of great horror imagery in Kubrick's film. The hedge maze, room 217, the blood, the flash cuts, the eerie camerawork. But it doesn't add up to anything that really, truly affects me.
