I'm not talking about the best here, or the one which is your most favourite and has had a great impact upon you - just the most influential on other film / media / society at large.
...and remember, it's the one that has had the greatest impact upon the world in the past 10-15 years (so Citizen Kane need not apply
).
I think a lot of Tarantino's work has been extremely influential, particularly Pulp Fiction. If you look at the way that narratives, timelines and witty scriptwriting has changed since then, it's impact can really be felt.
Also, Scream really changed the teen horror genre around! Yes, 'New Nightmare' influenced it slightly, but Kevin Williamson's script really kicked @$$!
Also, if you look at the parodies that came from both films, you can see just how far they pushed filmmaking and the way in which we view films.
