With the backdrop of World War II, the plot explores the historical fiction of Thailand's involvement in the war conflict and how the Japanese-engineered chemical weapon outbreaks, as well as how the Japanese military experiments on Thai soldiers.
The pace is rather uneven at times, where intense actions are suddenly interchanged with slow moments.
Unlike any typical mindless zombies, in this movie, the zombies retain a degree of consciousness and emotional depth, where they can communicate among themselves. This could be unacceptable to some audiences!
In terms of character development, only Mek and Mok (the two brothers) are well-developed, while the other supporting characters lack depth and growth, making it less impactful even though they are killed.
In general, this movie critiques the brutality of war that tears families apart. It also focuses very much on family bonds and the relationship between the two brothers, Mek and Mok. For instance, even in their zombie state, they strive to protect their family and loved ones. In short, the movie's emotional weight mainly comes from the strong family ties.
In summary, the movie offers a new and daring perspective on the zombie genre, infusing with humanity, social commentary, and emotional complexity. Oh ya, there is an end-credit, so remember to stay back for it!
