The time travel piece... HOT MESS! It was so confusing that it became distracting. I went into this series with no expectations, nor had I read the novel or seen the original. With all of that said, this fell flat. Honestly, if I was not a fan of Ahn Hyo Seop, I would have dropped it. There were too many holes within it where you have to 'assume' parts just so the next part could be considered. The ending was open-ended. The 'fix' towards the end tried to close up loose ends and felt rushed. The actors sustained the storyline. However, there were parts of the writing itself that seemed unclear or missed opportunities. Some parts missed the critical thinking and maturity of an adult. The love connection was touch and go. Yet, in the end...Did they really connect? I would ask the same for this series.
