My fav thing about this series is the progression of Sidney. She changes so much throughout the series. She's such a strong survivor, and even though part 3 was a bit hit and miss, i love that Sid was so damaged and haunted. In 4 i loved her lack of fear [for the most part], she seemed almost too comfortable and used to being stalked and aurrounded by death. That scene when she's running from ghostface and she's on the house roof with him was really well acted, she ran, but it was almost lazy running, like she was so bored of it all. At one point she turns to look at ghostface and there's this familiar look in her eye, like she's so used to seeing that mask that it's become second nature to her to simply turnback around and keep trying to get away from him.
I'm glad we didn't see her die in part 4, after all these years, i think it would have been unfair to see her not make it. After all, that is what her character represents in the series, survival. At this point though i think they should leave Sid alone, if a 5th gets made, it's time to give her character some peace. I don't mind if Dewy and Gail return though, they're good fun.
