The several minute scene in hell, while not close to what hell might be like and can be considered fake, it's still a pretty upsetting and frightening scene filled with disturbing images and happenings.
Mangled bodies are seen burning in hell.
A horribly disfigured person in hell begs Mary for help only to be taken away and lit on fire by a demon. The screams of condemned people are heard.
The appearance of hell is frightening. It is rusty, decaying and dark, with the only light coming from fires.
In hell, Mary's skin is pale and she is bound with a barbed wire gag that prevents her screaming from being heard. This is very upsetting to see.
