This movie is one of my all time favorites, I loved how Wes Craven took the Horror genre and just flipped it on it's head. This movie is very clever, smart, and keeps you on your toes with all the guessing of who the killer is.
I've watched this movie at least 20 or so times now and I always find something new in the movie that I didn't notice before.
The 2nd movie in this series is excellent as well but I would give the other ones(#3 and #4) a very hard pass. There will never be another movie quite like the first Scream movie and I am totally okay with that.
