Criatura Árdua (2023)

Both are action-packed shows set during the Japanese occupation of Korea. Both have an enjoyable romance subplot in the mist of all the fighting and killing.
Both feature badass fighter female leads.

While 'Gyeongsag creature' is more horror themed, 'Song of bandits' has a strong western vibes.

I felt same thrilling in both drama however in G-creature, I found more horror and thrilling. Both dramas represents on Korean independence, war between Japanese and Korean.
This drama have more cruelty then bridal mask..
