Predictable plot. Similar twists is repeatedly used. In the middle of assassin attack or dangers main casts can waste precious seconds to look at each other with love and talk stupid. Happens too many times spoiler. Like you're in the middle of a good dream and you're abruptly interrupted for a few seconds and then force to continue the dream which by this while isn't so good anymore.
Main actress is way too old for the role like a decade too old. Her puffy eyes betray her age. She is poor in comical moments. She isnt pretty. Casting numerous prettier and younger looking supporting and guest role actresses doesn't help her. Like making her age more obvious. Main actor role all too familiar and repeatedly used in too many period drama. High fighting skill, make little mistake, can predict all enemy's move like always and has bad childhood. Phui!!!
