Forgot to mention a few of mine...

'Before The Devil Knows You’re Dead'
'Pulp Fiction'
'The Last Time I Committed Suicide'

There Will Be Blood (just sounds cool)
Shaun of the Dead (a brilliant play on the classic movie franchise that fits in well with the parody of the movie)
Rebel Without a Cause (ironic and filled with meaning considering the story)
The Matrix (sweet and to the point)

Oh and how can I forget, Dinoshark vs. Crocosaurus...yeah.

Jaws (simple, yet awesome)
No Country for Old Men
Inglorious Basterds (pure badass)
The Big Lebowski

The Dark Knight - I love it because unlike all the other comic book movies that just stick with the hero's name and maybe something else, it tried something new with it. A play on the character that fit with the story.
Super 8 - simple and effective
Paranormal Activity - It hints at what's going to happen, but leaves you totally unprepared for the intensity of it.

The Year of Living Dangerously
