I love Korean films n Train to Busan is my fav zombie film.
Well, this is not as good as Train to Busan but nonetheless it is better than most zombie films produced left right n centre in Hollywood.
A prince returns home upon hearing that his elder brother has taken his own life.
While the king is busy with his concubines n the minister of military plotting to overthrow the dynasty, our prince has to face assassins, rebels, cries of poor peasants n hordes of demons (hybrid between zombies n vampires).
The demons r fast, terrifying n downright creepy.
The cinematography is top notch n the action scenes involving the sword fights r awesome. There is tons of decapitations, slicing of arms, legs, etc. but the gore is restrained.
The prison escape scene with the demons behind is pretty tensed n frightening.
