The Disappearance of Haruhi Suzumiya (2010 Movie)

Many people recommend skipping past Endless Eight. I encourage watching the entire thing if you have patience, or proceeding from episode (1) directly to (8) if your time is at a premium.

The core "Melancholy" story, Bamboo Leaf Rhapsody, and an understanding of Endless Eight are necessary prerequisites to appreciate the movie.
