As someone who enjoys sci-fi, I enjoyed it a lot. Plus, sci-fi and time travel wow i looove it. I particularly love the epic and cool action scenes, their amazing acting alongside great characters that they carries, the cinematography, the quick pace and of course the storyline that keeps me curious on how it will unfold, how it will take turn and twist and how will it ends. So, enjoyed it, for about more than half of the series. But then, the storyline started getting not as well written as it first is. There were soo many plot holes, that I kept questioning things. I try to not be logical for this series and go with the flow even though it doesn't make sense, but I can't help but question things. It just that the plot holes are too obvious especially in the final episode. wow, that episode really brings down my rating. So many things that I just can't brain and i feel like the writer kinda take a shortcut. all in all, i enjoyed it, not as well written as i expected, but it was good.
