I won't even go into the science and mathematics theories kinda thrown into the story to explain the dimensional travel, but I really, really liked this one. There were a lot of naysayers about this one, and I can understand to some extent as to what issues they have with this, but honestly, don't think about it too much. This isn't Inception or some other incredibly well thought out science fiction, so don't try to analyze it too much.

The story and cast made me think about Goblin. At times it felt slow, and the ending felt less than fulfilling and complete, but the overarching narrative was great, the acting was superb, the fight scenes rather lacking because of the slow-motion cinematography, and the emotions were well developed, complex, and endearing.

Taking Goblin and The King: Eternal Monarch into account, I would like to see Kim Go Eun in more fantasy romances. I think she is kinda a staple now. Now that Lee Min Ho is out of the military, I would like to see him in more similar roles. He has gotten a lot more mature of a look now than in previous years, which would make sense, so I want to see more of acting and roles like this.

Re-watch value is quite high, as I expect I will return to this again within a few months.
