Vincenzo was well written and perfectly executed in my opinion. No overload of romance to the point where it takes away from the story. Highly recommend.

This drama perfectly balances drama, comedy and violence without being overbearing in any aspect.

The ending perfectly captured the way that Vincenzo is neither a hero nor a villain, he still does bad things, and "doesn't care about justice," yet we still see him develop relationships with people and treat others with sympathy, which introduces a dilemma for the viewer.
A dilemma which Hong Cha-young also faces as she learns more and more about Vincenzo.
