1. Kill Bill (consider both volumes one film) 2. Scarface 3. Scream (1996)
I love that you put Scream up in there. That's a unique choice, but I totally understand it. Favorite movies don't always mean best
Scream had such a huge impact on me. Horror is my favorite genre and this film revitalized it at a time when it was dead. Not to mention the reveal of who the killer(s) were totally got me (although unfortunately, it's becoming predictable now within the franchise).
