Scream
The first and best Scream movie hands down. Whilst it isn't particularly scary, especially not nowadays, it still manages to be entertaining and great. As somebody who knew who the killers were before I first watched it, I found it to be a little predictable but of course I'll never know if my opinion could've been different if I hadn't had it unavoidably spoiled due to it's great success. Despite that it's still the best Scream movie and sets up a great trio - Sidney, Gale and Dewey. Love the movie.
