these kind of plot would only work if it took place in isolated place, or happened in limited timeframe (24/48H). it doesnt make sense to watch these kids, who watch half of their classmates heads blown off, just casually went to their home, hanging out, and back to school in the next day as if nothing happened


and the low production value just make the whole story not believable. they could'nt afford any extras to pose as other students, there are only one teacher throughout the series, the monitoring room are hilariously empty, the company lobby is just a terrrace, pc/laptops are always facing away from the camera, etc
