it was definately a twist no one expected, heck i barely understood all that blabber of the switching of the notebooks. also i think the author kinda dumbed kira down at the end, he would always have a backup plan if his original plan failed, like getting the eyes at the last moment. i believe he should have done so but hidden the fact he has the eyes, it would have save his life at least even if he lost half his remaining. that was his biggest mistake. so sad to see him die pathetically, well it was a good series i give it that.
