"Travelers" on Netflix.
Scientists from the future have the ability to transfer the consciousness of people from that era backwards in time to people in the 21st century who are in their moment of death. Essentially, personalities from the future inhabit bodies in the present that otherwise would have died. The task of these "reborn" people are to carry out missions that will cumulatively undo the damage that led to the downfall of humanity. Basically, these travelers from the future will try to save the planet one step at a time.
Very intriguing premise which focuses on the people and personalities involved rather than gimmicky gadgets and high-tech stuff. For example, imagine if you were from the future and you assumed the life and identity of someone that was married. Your spouse is unknown to you yet you are expected to drop right into the routine of married life to a stranger. Or how about in the future you are a scientific wizard in your 70's and you are put into the body of a teenager?
I've seen four episodes and while I'm not hooked, I am very interested and will continue.
