At death's door
Beyond the Door is Rosemary’s Baby, The Omen, and The Exorcist rolled into one, but without the subtlety, and the end result feels like a continuous rip-off. It was released in the UK in a re-edited format as Devil Within Her. If the intent is to horrify, the tone is totally off. The score is inappropriate. It’s right out of a detective film and that’s not what this is.
Creepy dolls, head spinning, vomiting; the film has scary and revolting moments, and it seems that’s where all the budget went. In fact, most of the good stuff happens in the second half. There are important pacing issues, but when the film delivers, it takes no prisoner. It took a shitload of people to write this; more or less eight of them. The end result is chaotic.
This is a patchwork of things that worked better in better movies. There are seemingly no connections between the key elements of the script. Possession is the only recurring threat. You have to be ready to sit through mountains of dialogue. If this film was thirty minutes shorter, and if it stuck to the essential, it might have worked, but, as it is, it’s a mindfucking borefest.
