It really is a wondrous show. The invention of time travel has been explored many times in many tv shows and films but I think this is the best of them. It's such an excellent story that is so gripping, sad and joyful. The whole plot is excellent with unexpected moments, heartwarming moments and chilling moments but the main thing that stood out to me was the characters. They are so unbelievably realistic which makes the whole show believable and makes you care for them when something bad happens to them. The chemistry between the characters sets the show apart from any other, each one resonates excellently with the other and creates many melancholic and gratified moments. The beginning of the show starts slow but soon picks up a steady pace and keeps you coming back for more. The ending, as excellent as it was felt a bit rushed, the second last episode introduces a new problem that they have to solve as quickly as possible which could set up a tense conclusion, but it lacks the duration I wished to have a strong emotional impact on me. Overall i thoroughly enjoyed the show and would recommend it to anyone, even if it is a sci-if it doesn't focus as much an time travel as I expected it to, it is truly great. 9/10
