Vincenzo is strangely violent serious drama while being also funny and comedic which is odd but you know what? I really enjoyed this weird mix and to me it somehow worked.
The story is layed down from the start so there are no ridiculous plot twists (or i dont recall one) which often plague korean dramas. Characters are lovable, the show have good pace and everything works good. The music was not bad but not great ( usually i remembr at least one track from each show and later listen to it but thats not the case for Vincenzo). Overall Vincenzo is a strong tv show.
There are some areas that could be done better in my eyes. There could be more romance (i like romance) but i guess its ok cause that wasnt the main focus. What bothered me the most i think were Vincenzo himself. Sometime Vincenzo italian quotes were cringey. I get it that Vincenzo should be a badass but Song Joong-ki doesnt actually look like badass his face is almost like a baby so i didnt buy it when he was telling some badass italian quote. Also i think i would enjoy it more if he wasnt that great in everything. He was like some kind of demigod and he was literally kicking everyones asses from start to finish and sometime i cought myself being sorry for actual villians. It would be nice if he got ass kicked sometimes or if he had some flaws. On the other hand FL was great. I enjoyed her dark side and i actually would prefer if she got even more evil. Villains were... well they were there and they did bad things but they never actually won a single arc against Vincenzo which is sad. Also the main female villian was just... weird. I never understood what were her motives. She is the only character which didnt make any sense to me
