Paprika

Stunning; Madhouse always does good work and Kon's movies always produce some fun reality bending sequences.The voice cast is headed by Megumi Hayashibara, probably the most prolific and well known female seiyuu ever, with roles such as Rei Ayanami (Evangelion), Lina Inverse (Slayers), and Faye Valentine (Cowboy Bebop) to her credit. Akio Ohtsuka and Koichi Yamadera, Batou & Togusa of Ghost in the Shell fame, both play major roles as well. All do a fabulous job as usual, but Hayashibara really shines in her Paprika role.
