A problem with time travel stories is that, if you are allowed to go back in time and repeatedly change history and rewrite the future, then there's the risk of a never-ending loop. At best it becomes a logical conundrum. At worst the story is tedious and even pointless. In this show, you don't actually time travel. Instead our heroine found herself with the ability to contact a specific person in the past and attempt to change the outcome of a crime. Fortunately for this show, it doesn't abuse the time travel too much. Instead it tries to leverage them to maximize the intrique and explore the true character of the protagonists and villains. At times you wonder who is the good guy and who is the bad guy. Another bonus is the lack of romance or subplots so we are focused on the main story, which is overall sufficiently thrilling, if rather classical, as the powerless struggle against the powers-that-be and other wannabe power players. Give it a try if time travel and political thrillers are your thing.
