This show tried to be train to busan so badly like it desperately wants to be compared to it. The inspirations are clear as day.

Comedy, why?: i think there are kinds of shows that doesn't need comedy, this is one of them. Comedy could work in zombie shows/movies, but a quirky drama type of humour is just not the tone that this show needs.

Stupid side-plots: Why did we get an entire side plot for every episode of some live streamer trying to survive, it was neither compelling nor interesting.

The show also tries a military sub plot, that makes sense on the surface, but is a waste of time

Deaths: most deaths in this show are sacrifices that help the friend group progress but when EVERY death is a sacrifice the meaning of those deaths becomes pointless and meaningless, it also shows how the writers are incompetent at creating a meaningful death.

Villain(s): Lee Nayeon is unrealistically evil, it was completely unnecessary for her to kill Gyeonsu, and then she was sad about having no friends, her character should've been a way to show how selfishness and greed affect human relationships.

Gwi-nam has no other depth than other being evil as hell

GOOD: the cafeteria scene (well-made action sequence)

It's unfortunate, i really wanted for this show to be a good zombie movie as Koreans has made their mark for creating well-crafted zombie shows and movies with Kingdom and Train to Busan, but this will never, ever should ever be considered even a being a decent show nor should it get second season.
