This drama started of awesome, with lots of thrilling twists and turns. Its interesting to see the consequences of his time travel and how they reach farther than you would think with one small action completely changing someone's life and effecting so many others aswell. There are lots of different elements that combine to make this a great drama; comedy, action, family and romance. While I loved the drama I was disappointed with the ending, which was left as a write your own or believe your own ending and also the drama got a bit confusing at the end too without giving any spoilers thats the most I can say. Overall while I thought the acting and everything was good I probably would not rewatch, firstly because I dont really rewatch dramas anyway and secondly because I felt cheated by he ending.
