This drama was already promising at 24 episodes, but it should have been 16 episodes. Repetitive flashbacks were extraneous. I don't think we needed to be reminded of these scenes, The ghost town where it was staged was either a deserted war-torn or flooded town, or some ugly CGI. The bats vanished fast in the early episodes, and the zombies must have gone to sleep. I am surprised that the stranded travelers did not explore the town for supplies or better accommodations. They just stayed in the hotel, run down in some places. The store where Er found the sneakers had clothing hanging in the shop, although they should have rot in twenty years. Was the train track sealed off on both ends, or where they just lazy, to try to escape from the bats and zombies who took a snoozefest? The blue ocean, which I am sure was CGI, was the prettiest view. The production quality was bad in many episodes. Extreme closeups with a bland expression do not constitute acting skills.

After bingewatching the first 16 episodes in the last three days (in October 2023), I skipped to the final episode. The timid teacher was the the mastermind. LOL I don't think I missed anything important. This was my Halloween entertainment.

Final rating: 55
