My version of Sally includes the dress she's wearing. That was my Hallowe'en costume that year! Wish I had the skills to pull off a Lady Groot costume, though. i can't really sew, so I kind of just hack things together.
Also, I cannot stand horror movies if they're mindless slasher flicks. I actually enjoyed Psycho and The Shining. They were scary, but they didn't affect me the way the Scream movies did! The slasher-y ones somehow manage to upset me and bore me at the same time. I need cerebrally stimulating scares. Because I'm a snob.
