Because leftist-themed period dramas never fail

Top-tier actors like Yoo Hae-jin, Park Hae-il, and Lee Min-ho have flocked to "Assassins." The fact that actors of this caliber have gathered for a single project means the box office calculations are already set.
A detective and a reporter question official announcements and dig for the truth despite pressure from those in power. This framework itself is a "safe asset" that has never failed in the Korean film industry for decades. The flow is similar to "The Attorney," "A Taxi Driver," and "1987."
Since both audiences and critics are lenient toward this genre, and award ceremonies follow suit, it is a choice where actors have nothing to lose. The problem is that because this formula continues to work, top-tier actors are racing to appear in them. I wonder if the established formula will actually apply to "Assassins"...
