Very tough call, but I'd have to say Lord of the Rings for the simple fact that I recall how deeply moved I was by the film(s). I'd just come out of a dark time in my life when the very fact that I'd see my next birthday was in constant doubt. I cried constantly toward the end of Return of the King, I'm not embarrassed to admit. I wept for joy that I'd survived crushing despair and suicidal depression to witness the concluding chapter of one of my most cherished authors' work transformed with reverence, awe, and mastery into a film of tragic power and sublime beauty. I remarked to my companion as we left the theater that I believed Tolkien would have been pleased with and flattered by the end result.
