I've never watched Kubrick film, I borrowed his Essential Collection from my girlfriends stepdad. I have a bottle of Jim Beam and a few hours til I need to sleep..what should I watch?

*a Kubrick film

I have everything from Spartacus until Eyes Wide Shut.

I've heard a lot of good things about a lot of his films, but where would be the best place to start?

Thanks guys and gals.
