It's a wonderfully eccentric film with endlessly quotable dialogue and uniquely bizarre characters that has garnered a massive following over the years.

Quentin Tarantino's Pulp Fiction is a postmodern masterpiece that weaves together multiple interconnected storylines from the Los Angeles criminal underworld.

It's a cool, clever, and endlessly rewatchable film that plays with genre conventions and boasts an incredible ensemble cast.
