This what happens when you don't have good enough budget on cgi and your director's experience is only rom com shows. So, the only option is a cheesy and campy show like shark nado, zombie nation, or any show on syfy channel. Therefore, the show should not be judge as a serious horror. Ep 1 establishes the cheesy tone when they play warrior's music in background and Lee Eun Hyuk is spraying fire hydrant in monster face. It's a joke and this why they play it in every time heoric moment happens.

Most of the characters are stale and common tropes, which is the main issue with the show and not a failure adaptation of the character relationships. Like, who cares if the show fail to adapt character relationships, when your main character Cha Hyun Soo has the most overused backstory with family dead, bullied in school, and same boring personality. This isn't even spoilers because this literally every main Asian boy orign story. It's raining and there's either sad piano or violin playing in background and someone they care about dies. At this point, I am starting to think all of the boys in Asia real life are bullied and their families are dead. Furthermore, you got Captain smarty pants, Wannabe gangster dude, Sword dude, Healer girl, etc. Imagine Cha Hyun Soo had a normal personality and his family was alive that would be the real horror.

However, there was a couple characters that were entertaining and what kept me continuing to watch. Han Du Sik made interesting combat weapons and traps with house supplies, occasionally joke around like about his disability, and he is decent actor. Ahn Gil Seop is not your typical grandpa character, who are usually nice, weak, wise, and formal. He is kickass grandpa, had a dark sense of humor, and jokes about his death a lot. They are the main reason why this show was decent to watch.
