I heard a lot about this drama, so I just decided to check it out. I completed it with great difficulty because of unnecessary dragging. It's not the worst I watch but it's not the best which everyone claims.

If you are a kdrama newbie, just watch it, it's an average drama with good entertainment. But if you are a regular watcher of classic thrillers like Stranger, Flower of Evil, Children of nobody, don't waste your 20 hours.

PROS -

Good Direction/Cinematography - The budget and thought both are present in each shot of this drama. Any shot of drama compel you to watch and attract you. This is type of direction which attract you to watch drama just from teaser or short clip in fmv

Music - Let's talk about music, each and every ost as well bgm just create magic on screen. Definitely in top of my list.

Acting - Acting is very good. Every actor give their best in margin and according to their character but only few get shine . Kwak dong yeon stood out for me with his subtle acting.

CONS -

Story - Bad vs Good - it's old, let's make it Bad vs Evil. Meh, what were they thinking. This story can get pretty decent if they ended drama in 16 episodes. There are unnecessary side characters, clashing of morals of characters, as well some annoying characters. Vincenzo can be a good character-driven plot as the title name suggest but sadly it is the action-driven plot. I can't connect to any of the characters, they just do action but I can't feel for them. It's the same with every character, giving an unnecessary dark past to characters does not make them vulnerable, you need to make the characters connected from the audience. Vincenzo character leaves no influence on me, no remembrance.

Comedy - There is suddenly a new trend in the kdrama industry to include comedy with every genre. They just stopped making dark thrillers. One or two puns were decent and I chuckled but comedy overall the place break the momentum for me

Mafia in Genre - Where? Just one question? Where is that element? The gun Vincenzo hold.

Acting - Acting have cons too, SJK is a pretty actor who has his class. Either it is character or acting, but he left no impact on me. There are few actors and main roles who leave left a longtime impact - Mo Tae gu of voice for example. Hence no character in drama can be termed as iconic. Female lead annoy the hell out of me, I don't want to disregard her acting, she did well with character but it's just OTT

Hype - This is not dramas cons but of audience. The audience hyped some dramas like it is the best thing ever which make people expectations high. But it went flat when you tune in to show ,when you realise there are better options to watch.

Overall, I am not telling you not to watch, if you have plenty of time, go watch it and enjoy the action. But if you have less time and you watch classic thrillers, please don't go ahead.
