If you like Sci-fi shows, you SHOULD NOT miss this one. At first I was little skeptical because of the 7.6 rating, but let me tell you, this one deserves a 9. The story starts with something, but it evolves into something we won't expect. And it's a beautiful love story. From the beginning itself, we'll start feeling "James cole& Cassandra Riley were meant to be together". There are some TV shows in which we would automatically love to associate ourselves with the hero/heroine, their relationship. This is one of such shows, we can say, love that keeps the show binding together. Another very important aspect of the show is that it'll change your concept of time. It provides the scientific concept that The past, present and future exist simultaneously. We see time as something that only moves forward. But this will change that concept. It's not really frictional, there are scientific theories & concepts that suggests that present or future can affect the past. Another concept that this show provides, that we live in multiple timelines, that too is supported ( or suggested ) by quantum physics. This might be a little bit difficult for some people to understand or it might seem too fictional for some, but to such people, I suggest you to learn more about scientific theories/ thought experiments such as multi verse, double slit experiment, Schrodinger's cat etc. Once you understand all that, you'll find the show much more interesting.
