I haven't watched any horror sinema au anything, but the scariest was probably The Disappearance of Haruhi Suzumiya. The part near the end with Ryoko...*shudder* Jesus Christ, she just flew up with a kisu and stabbed Kyon while getting all lesbian-like on poor Yuki, who was just kind of freaking out. DAMN, SHE SCARES ME zaidi THAN RUSSIA AND/OR BELARUS!!!
