Once Again benefitted a lot from the star-making performance of Moon Ji Young but it's muddled storyline, frustrating dialogue and lack of a real stake stands out the most, dragging the entire series down.

The cinematography looks nice but there's really not a lot to work on with this material, but it did work for the little material they were given.

Moon Ji Yong as the main lead was fantastic, he looked very committed and that reflects well on the screen. His facial cues and expressions are very impressive.

As for the storyline, the whole thing was so muddled and confusing. It fails to make the audience pay attention or even care. I finished the series not feeling anything, just indifference. It didn't make me want to care enough for the characters.
