I love Scream. Love love love it. It's one of my favorite movies, in fact. I never once considered it a horror movie of any kind though. I always looked at it as a social satire of the slacker generation. We know everything...but we're too damned stupid to get off the couch. More wrapped up in a world of technology, pop culture and gossip than what's going on right outside our own door.
If anything, I'm impressed by how well those themes hold up 12 years later. The use of cell phones and the spawning of the tmz generation has actually blown what I thought coming out of the movie over a decade ago up by monstrous proportions.
