I'm always fond of Mafia related stories, shows and movies and to say that I have great expectations for this series is definitely not an understatement. When I watched the trailer of this show, I was blown away with the acting and cinematography until I eventually watched the series and somehow my view of the show albeit slowly changed...

The Pros of the series are definitely the cinematography, acting and OST... The actors / actresses did their best in portraying their characters well.. The soundtracks are also good and I'm definitely loving the songs...

What really fell through for me was the plot and illogicality of the characters.

The story got really really REALLY draggy too.. There were a lot of scenes for me that were unnecessary like you know the feeling that you're just watching some fillers before you get to the main point of the story.. That's exactly what they did with Vincenzo.. For me, the show could have just ended with only 16 episodes or even 12 episodes because each episode has more than an hour of running time... The 20 episodes is just too much..

Aside from the plot, the villain in the story got downplayed... Like really downplayed..
After watching a lot of crime thriller kdramas that have psychopathic killers, Vincenzo has one of the most unique villain in all of the shows that I've watched and I'm sad as well as disappointed that they didn't use the full potential of the character. The villain in the story was described to be cunning as well as a genius with his eccentricity and someone who is SUPPOSED TO BE ON PAR with Vincenzo, yet they made his character underwhelming in a way that if I summed up all the scenes that the villain did, he didn't have any scenes that justified his character because Vincenzo always won and like everything seems to be pretty convenient for the main character etc... The show really favored the hero to the point that it had me questioning a lot about what was even the relevance of the villain being on par with Vincenzo but not even having a chance to shine.. This really frustrated me... If you're going to make a series with a premise like this, it should be balanced... The wasted potential of the villain's character got me facepalming to no end.. Even the main character (Vincenzo) had a lot of out of character moments... **sigh**
The female lead also has a sassy character but the way they introduced her was just so bad and it annoyed me... It felt like she was over reacting too much or trying too hard and it wasn't even funny.. Although, I'm glad that her character had some improvements in the end...

I also find the Geumga Plaza residents to be annoying.. I find some of their scenes to be irrelevant... This would probably the show which I will comment that it has too many side characters that the show definitely does not need.. While the Geumga Plaza residents are a source of comic relief, I find it to be awkward in this show.. Like it doesn't fit the whole Vincenzo thing...

Another thing is that I understand that this show is a slap stick comedy with a sprinkle of mafia.. but seriously though, the mafia thing here is just mehhh... Not even a MAFIA genre in all honesty.... They sugarcoated the mafia tag here and if you're looking for a serious show.. then this would be not your taste.. The comedy, action and seriousness of this show is not balanced well... Too much comedy in a show that started off in a serious and bad ass note...

And also, an important thing that we must also consider in the series is the fact that there were some scenes (the homophobia and misinterpretation of a gay character) that happened in the show that left a bad taste to the LGBT+ community. The fact that this issues weren't even addressed well disappointed me. In our society today where media is a powerful outlet, viewers can be easily influenced by what they see or hear and I find it to be disappointing that yes this show is popular however, it failed to address or give respect or even importance to the LGBT+ community.

There were a lot of questions that weren't even answered well.. I've always been curious of the past of the main character and although they used flashbacks for Vincenzo's past but it's technically not enough.. It would have been better if there was an episode or even 2 episodes in which we really got to see how he grew up in Italy, eventually meeting his "father", joining the Casanno family and becoming the legal adviser of the family...
Furthermore, it would have been better if they also showed the back story of the Babel Siblings - how Han Seok became an eccentric psychopath, how his brother put up with the expectations of the family and what did their father felt or do at that time. These would have been more interesting to see rather than those unnecessary or irrelevant scenes in the series...

In conclusion, Vincenzo had an epic beginning with the main character starting of the story in a bad ass way but in the end the inconsistencies of the plot and characters got the best of it.. This is entirely my opinion so I won't be discouraging people to watch it.. but I just want to say that kdrama writers should try to improve in writing their characters and plot.. We need female leads that are not just supporting characters.. We need main characters and plots that are consistent / logical... And lastly, we need villains that are on par with the hero because with that, it will leave an even deeper impact or impression with the audience / viewers..

P.S. I'm not hating the show.. This is just my opinion and I won't discourage people to watch this show..
