12 Monkeys

The premise: In 2043, a man is recruited by a team of scientists to travel back in time to 2015, in order to stop the release of a virus that would result in the deaths of seven billion people by 2017.
12 Monkeys is a remake of sorts of the 1995 Terry Gilliam film starring Bruce Willis and Brad Pitt. Because it’s a series with 13-ish episodes per season, a lot more attention is paid to backstory and character development. You know, if you’re into that sort of thing.
