Honestly, if you are trying to find another "Train to Busan", you won't find it here. The plot revolving a rebellion for the throne takes way too long to develop and ends up completely unnecessary in the development of the movie. The effects of the vampires (dunno why people are trying to say these are zombies, because they have all the characteristics of vampires) are decent at best, but the action scenes are way too few and short for a 2 hour film. I had to drag myself during the duration of it since 2/3 of the movies I was completely bored from the rebellion arc that ends up being useless. Just watch if you have 2 hours to spare, but be warned that most of the screen time will be chit chat
