A lot of questions they really didn't answer in this movie
- Why is it that the living could also see the Handbook for the Recently Deceased, touch it, and read it? Shouldn't it have been a book only the dead could see, touch, and use?
- Why did they only show people in the Netherworld waiting room who had died tragically in accidents? Was there a waiting room for each type of death people suffered? Where did all the ghosts of people who died naturally (like elderly people who died of old age ailments) go? Did they have to haunt houses for 125 years too?
- Why only 125 years? And what were the Maitlands gonna do after their 125 years was up?
- Was there a proper afterlife the spirits of the dead could go to once the "paperwork" had been filled out?
- If the ghosts could change the look of their faces and bodies, wouldn't it have been possible for the ghosts in the waiting room to change their appearances so they didn't look so messed up from their deaths?
- What exactly was Beetlejuice? Was he once human and died in the plague 1300 years ago? Was he always a ghost? Was he a demon? Why did he have magical powers? How did he get them?
- Does anyone think BJ was lying about his credentials when saying he went to Harvard, Julliard, and experienced the Black Plague?
- Why would marrying Lydia allow Beetlejuice to re-enter the world of the living?
- How did Barbara get that sandworm to let her ride it, and how did she get it to bust back into the house? Where did it go after she got off and it went through the floor?
- Why did the Maitlands suddenly start to age and decay after being brought back to the world of the living? Was it because they didn't have real bodies to return to? And how was Beetlejuice able to "fix" them?
- What is the nature of the curse Beetlejuice is under? Why can't he say his own name, or write it correctly? And who cursed him?
- Why does it seem like Juno is the only one counseling all the dead coming through the Netherworld bureaucratic system? Surely there are other people with the same job she has, right?
