Just finished Vincenzo last night and I personally enjoy the whole 20 episodes eventhough there wasn't that many ear catching soundtracks. I think it was a great and smart ending. I love how they wrapped it up and stay consistent with "Only evil can punish evil". Cause that's the main point of this drama. It's so satisfying to see all those evils punished in the end. Sad but in the end, our best boy did not die in vain. I personally think with or without romance, it would still turn out good but you know you gotta spice it up to make it delicious. Great one.
