Sarah running
I glanced through the comments and didn't see any other one about this, but I remember when this came out I was working at a move theatre, and we used to mock the way Robin Tunney runs. I am rewatching it now and while she's trying to get away from Chris, and then when leaving the store after trying to invoke the spirit, it's like she just holds her arms out awkwardly to the sides. Yet when she's running through her house, her arms look a little more natural. (I'm not counting the slit wrists scene) It just always seemed really weird to me.
