An absolutely wonderful experience, Paprika is intelligent, complicated, visually stunning and pleasing, and interesting.
The plot revolves around the theft of a device that allows people to enter people's dreams and help them make psychological breakthroughs. The thief begins using the device to plant dreams into people's minds, driving them into a suicidal frenzy. It's an interesting thiller/mystery.
The Blu-Ray looks fantastic, with a sharper picture(although I warn you its not immediately noticeable, cartoons aren't necessarily designed for Blu-Ray). The sound is fantastic, especially the haunting melody of "Parade". The menu is non-intrusive, allowing you to change languages/subtitles/scenes without needing to go back to the root menu. It really is a fantastically well programmed disc. The additional content is unimpressive, the usual docs and dvd commentaries, so if you're a stickler for extra content, you will be disappointed at the mostly empty blu-ray disc.
