Sephiroth was a lot more interesting in the first half of the game, when everyone spoke reverently about what a godly soldier he was, and then a series of gruesome incidents began occurring that were attributed to him either by eyewitness accounts or the sheer brutality of their execution, although he always remained out of sight. The trail of blood, the President found slumped on his desk with a sword in his back, the Midgardsorm impaled messily on a tree, the slaying of the cargo ship crew leading up to his ghostly first appearance... This was all great stuff, imbued with a sense of mystery and creeping horror that was gradually eroded as the story progressed and you began to find out what his whole deal actually was.
