Korean Drama "L.U.C.A.: The Beginning" had an explosive start, but halfway through changed route and became a completely different drama.

First of all, the main idea of the story is pretty interesting. The sci-fi element was also well managed and didn't lower the quality of the drama. The performances were pretty great as well, and, especially, the action scenes were top-notch.

However, the ending episodes were a completely different drama, with a rom-com family drama twist. That, along with the female lead being an annoying, selfish and arrogant character, along with the miscasting of the male lead, though the actor was excellent performance vice, were the factors that ruined the drama. At least the drama was short and didn't far stretched the story.

So, overall, five out of ten.
