I watched Vincenzo when It was airing and it was so exciting. Each weekend I got my laptop and my speakers to watch and have a blast. The episodes were a roller coaster of emotions, you could be laughing, then shed a few tears, then get angry, cringe and even feel disappointed. This drama just had me in my feeling. through the week I would watch back my favourite scenes or even rewatch an episode.
All the actors were great in their respective roles.
Acting
1. Vincenzo (Song Joong-ki) had so many different sides to him and his eyes would especially bring out these different sides of him. He could be scary mafia dude, but cute and romantic hubby, he could be silly. His face just always showed what mood or character he was portraying.

2. Hoong Cha-young (Jeon Yeo-been) executed her role just how she was supposed to be. A shameless lawyer who would do anything to win. She made me laugh , cringe and sad throughout the show.

3. Jang Jun Woo (Ok Taecyeon) the first half of the show he nailed his innocent clueless intern role to a T. But then he was the vilian and also that spoiled rich little boy who liked to smash and destroyed what he could not have or control.

4. Choi Myung-hee (Kim YTeo-jin) I hated her so much each episode I was just wishing she would be killed how cruel she was and how she could just order people to be killed just like that then sit to eat or dance. Because of this I think she did a fantastic job.
The Tenants - they were so selfish at times, but then each one of them ended up showing how useful they were and that they were worth fighting for in their own little way. I especially liked Tak Hong-shik, Mr. Nam and Seo Mi Ri out of all the tenants. Mr Tak, because when he stated to fight with his scissors; Mr. Nam for his awkward, adorable and usefulness and Miss Seo because she was just this weird piano player but then bam Top Hacker extraordinaire.

This show had a little bit of everything, comedy, action, angst, subtle romance. It dealt with trust, family, loyalty, fairness in the society and the legal system, cooperation and so much more.
Give the drama a try you either love it or hate it. You might think it's average and that just fine.

All dramas are not made equal and everyone does not need to like everything.
