Clearly, they didn't have much money although the effects are pretty good. I just got a little annoyed with the characters just staying in the awful place with the mold and with the dangerous guy when they could easily walk somewhere else or at least breathe fresh air outside. Maybe if they couldn't exit the building so easily or if they established that people exposed to black mold don't have the common sense to get away from it then I could accept their actions more easily. I was hoping there would be transforming or some kind of unique monster but it's more just a drama with some tension. I was pretty engaged though.
