There's more than a dash of soap opera in Red Swan.
Superficially its looks like a thriller with crime/political overtones. In practise however, there's a syrupy love story replete with a handsome hero and evil antagonists, such as the overcooked CEO mother in law character.
The results a series that has its moments but mostly feels like a rather hammy romance novel, than anything else.
Acting is decent, save some of the over the top characterisations and production values, are high.
In summary, if you are in the mood for romance Korean style then this may appeal. If you want a hard nosed political crime thriller, I'd suggest looking elsewhere.
