I'm embarrassed to say that the first time I saw Scream 4 I didn't 'get it'. I enjoyed it, but I didn't see beneath the surface of the film. I didn't get how far the film went with the reboot/remake theme. Every character from the first flick has a representative in this flick. Jill is Sid, Hicks is Dewey, Kirby is Randy, etc. It's really genius. And then the film takes these familiar Scream archetypes and flips them on their heads. The second viewing of Scream 4 really cemented this one as my favorite of the sequels, and I wonder how many other people would benefit from seeing it a second time. As much as I loved it the first time, the second time was one hundred percent more enjoyable. Everything I loved about it the first time stands true. The opener is awesome, the killer/killers and his/her/their motive is fantastic. My one complaint stands true. A horrible out of place line ruins the best death in the film (and possibly the series.) The new cast is great, and their dialogue is just as rapid fie and witty as you've come to expect. (From the good Screams at least. So no wooden crap-tastic Scream 3 non sense ) Seriously, if you haven't seen Scream 4 go see it, or hell the DVD will be out shortly, it's already in cheap theaters. If you have seen it, see it again.
A by the way here, I don't think my earlier theory was right. I thought that Kevin had been forced to change what I have discussed here before as a spoiler. It didn't turn out that way in the flick, but I thought that I had still been right, and Kevin had been made to change it and that's why he left the project. I no longer feel that way. Instead I think why Kevin left is they forced him to change the ending. I think Kevin's original script had it ending after Kirby's house. Where it fades to white.
