Gah, I feel so ashamed. Yes, that's right. I watched Charlie and the Chocolate Factory and got scared. In my defence, I was a kid back then, and yeah. xD
If you're looking for a scary movie, I recommend browsing through Asian movies. There's a wide variety and I recommend the Filipino Film 'Feng Shui' about a cursed feng shui mirror and everyone who looks through it dies with your chinese zodiac animal in sight. Like, if you're the year of the dog, you are gonna get killed by a guy with a dog tattoo or if you are the year of the horse, you will fall in your death with a horse nearby.Very nice, it was scary for me, but I watched it when I was little so...
Though, I also recommend The Experiment or The Fourth Encounter (or was it The Fourth Kind? idk but it stars Milla Jovovich) anyways, both are not hack and slash films but psychological thrillers. One about alien abduction or the fourth encounter, that got everyone in the town crazy, and all of them having recalled an owl looking at them the night before they kill themselves or they kill other people. Writing about it gives me the goosebumps. It was supposedly based on a true story, but it was just a publicity stunt. The other one is The Experiment, starring I forgot who but he's Iron Man, about a hippie who sign up for an experiment that includes human behavior about the environment of prison cops and prisoners. The movie version of The Lord of the Flies, I think. What's more, it was a remake of the german film, which was based on an actual experiment back in 1960 something. So yeah, it was based on a real life event.
