The Seventh Seal
Andy and I recently watched The Seventh Seal, he for the first time and I for the first time in several years, and it was amazing: deeply symbolic, dense and multi-layered with two extraordinarily moving scenes (the burning at stake and Death at the castle) but at the same time accessible and easy to understand.

Unlike Persona, which although entirely gripping, left me with the humbling feeling that I didn't actually understand any of it.
