There was a time when I could say that Scream was my favourite movie of all time. My tastes have changed, but when I saw the Bluray pack with the first 3 movies for around $20... I almost wet myself.
It's an amazing play on previous slashers, while taking itself seriously as a slasher flick. 2 and 3 degraded on the series, but it is still one of the better, funnier, suspenseful 'horror' films of our time.
I will see 4 in theaters easily. I've seen all the others on the big screen, even seeing the original at a midnight showing years after it was on video.
Not a spoiler, but...
