I had avoided the Blu-ray of Studio Ghibli's saddest (and arguably best) movie ever, Grave of the Fireflies, due to not trusting its unknown-to-me American home video distributor, Sentai Filmworks. What an idiot I am. Don't mind the washed-out color of the cover art: the disc is gorgeous, and features a new English dib if you care about those.
This is a great film, and one of the greatest in the history of animation, but be forewarned that it is both beautiful and profoundly depressing. It opens revealing that the two kids you're going to fall in love with are already dead, and that the movie is about their struggle to survive WWII Japan. Even with that setup, it has my highest "what do you mean you haven't seen it?" recommendation.
