From what I can see the general concept is that 2 brothers get to bring their father back to life for 24 hours to spend one last day together.
Now granted I have not lost a parent but I have taught several children who have gone through this horrid experience. The advice given is always to make it clear that death is final and that the person cannot come back no matter how much the child wishes it.
So surely the plot for this film is at best not well thought out and at worst it could give false hope that seeing their parent again might be a possibility?
Aibu or am I massively over thinking this?
