The person who makes the jewellery linked to in my sig says she wouldn't want to live in any of the Lord of the Rings films. Or anything 'cobwebby'. So I suppose that includes Arachnophobia and Charlottes' Web.
Personally... Silent Hill, because I quite value my life, thankee. The Matrix, because I'd be sorely tempted to go with the Ignorance is Bliss philosophy... and Life of Pi. Because I'm much more of a dog person, really.
Silent Hill. It's just a creepy place to live and every time the siren would go off, and everyone would run to the church for safety, I'd die. I can run for a long time, but not very fast. Plus I trip a lot. Pretty sure pyramid head would have my skin after one day of me living in Silent Hill.
At the moment I'm a bit tired to think of examples of my own for the most part but I'm sure Night of the Living Dead wouldn't be a cakewalk.
Enjoy
