Leftovers is excellent, the second season was the best season out of any show that I watched last year. It is a drama first and foremost though, and with its pacing, its not for everyone. The first season especially is a bit frustrating as the show seems unsure about what it is trying to do. The first season still has some excellent episodes and very much worth watching IMO. However, the second season is outstanding, start to finish. The show underwent somewhat of a revamp after its first season, and the second season introduced some big changes. If you like great dramas, its worth watching. The Leftovers' third season will premiere in April 2017 and it'll be the show's final season. So overall, it will be a pretty short run for the show.
