Hi Tudwell,
I'm a big Ingmar Bergman fan.
The Seventh Seal is good, about the silence of God and facing death (Death is actually a character) and has a good amount of Biblical allegory in it. Pretty interesting. My favorites of Bergman's are
Scenes From a Marriage and
Fanny and Alexander. Scenes is the most brutally honest and accurate film about relationships I've ever seen. The last film he made is a sequel to Scenes called
Saraband, that is excellent as well. Others of his to check out are
Wild Strawberries, Persona, and Cries and Whispers.
Since you liked
Pulp Fiction and are open to foreign films you should definitely check out
Breathless by Jean-Luc Godard. It is the grandfather of the post-modern, stylistic film.
BTW, forget Blockbuster, get Netflix, the selection is great.
