TLDR: Vincenzo is a dark comedy about anti-hero mafia consligere who delivered justice, in outrageous crooked ways, with loveable characters (looking fly as hell), coupled with interesting villains. Being a comedy, every episode would have something funny. This at times back-fires, as it created a couple inconsistencies in characters, albeit endearing and entertaining. Also, there are a few unnecessary characters that make this drama a little too dragged out, perhaps to fulfil the 20-episodes arc. All-in-all, a fun and entertaining ride!

*spoilers ahead*
What the show did well: The show's premise was indeed outrageous from the get-go. It could have gone so terribly wrong if not for the spectacular VFX (Italy scenes) and acting (Song Joong Ki) in the series. Besides VFX, the action scenes were shot really well, probably one of the best action kdramas in my opinion. Secondly, the writers have definitely provided endearing main characters for viewers to root for, especially the Geumga Plaza residents and Hong Cha Young. The drama's initial surprise of innocent-looking Jang Joon Woo being the mastermind of Babel was really good, and his psychopathic character and his spiraling out-of-control was entertaining yet intimidating to watch. Lastly, my boy Jang Han Seo deserves better (more so of the actor playing characters that have happier endings). I really liked the character development for most of the characters, including Jang Han Seo and former Babel minions. Last but not least, the soundtrack was dope. Some of the tracks being classical-influenced amped up the pompous or outrageousness of the drama, which is pure entertainment.

What the show could have done better: I wish that ex-Prosecutor Choi was given a better storyline. Heck, she could have been the main villain or forge a different path (aka joining the good guys/not being the subordinate or sidekick). In earlier episodes, we see that she was a boss ass bitch (albeit terrorizing) in the law firm. Yet, in later episodes we were given a Harley Quinn-ish character that stayed by her Joker (aka Joon Woo). While I do understand her character development, it felt like she was shoved aside to make way for Joon Woo. Same for Hong Cha Young, I also wish she could have shown more of her lawyer skills/chops instead of Vincenzo always saving her ass/the day. The last few episodes had some random ass moments/subplots that felt like fillers instead of character or plot development. Also, I felt that there were a few too many episodes ending in a cliffhangers that results in unfulfilling plot devices.
