Was the Underworld a good or bad place?
In my opinion it is a bad place.
Osiris is the supreme ruler/God of the Underworld and evil. :[
There are many natural features in the Underworld Paradise. Some features include mountains,lakes and forests. "Paradise" also holds hazardous things such as lakes of fire and a mound in which held a head called Isis Flesh. Paradise isnt really paradise at all in my opinion!.!. Another reason it may be a what you call bad place is because Osiris is the ruler. Would you want a ruler who is also the ruler of evil?
