Idea of past life is good, not this format though
I dont understand why they have to make every second show some case based detective show with a token twist. There is almost no room for character development in these kinds of showa and they usually end up cloning eachother. This show had nothing good going for it either to make it past the 1000 other detective shows out there.
Past life could be a interessting concept though, but instead of making it a twist in a *beep* case based detective show, why not use it with timelines in assassins creed series?
