The characters do not behave like morons. The behavior of people quite sensible for the situation. There is nothing explicitly expressed here, there is a strange problem with the child and the mother who, according to her, does everything to keep her son alive without considering the consequences. For a B-grade cinema, this is quite an interestingly developed plot of supporting characters. The biggest drawback is probably that it's not very scary. On the plus side, there is a slight suggestion at the end of the film that maybe we didn't quite see the same thing as the main character, but I think it's more of an attempt by the medical services to justify the phenomenon in general. As for me 6/10, not great not terrible, I do not regret that I watched it but do i recommend it? I don't know.
