Never have I given a drama anything less than an 8. This does not deserve even a 4.
One big bad company (Mafia TL) ruins people's life in the form of intentional/accidental industrial accidents. Protagonist and side-kick investigate with/without inside help.

Could have forgiven this time-tested story had they remained true. But no.. they had to make the side-kick a comic relief and serious at the same time which terribly backfires. A lot of seriously dysfunctional relationships with everyone being either a bad person or a moron.

Finally the Michael Corleone female version takes over the Mafia company from her dad and things .. uh.. go on I guess? Highly idiotic drama despite the cases themselves based on real life accidents.

Watch only if you have time to kill.
