Here is where Michael Keaton performed in a convincing role as an afterworld agent bent on getting a property back to a ghostly couple after their home was sold and a new couple moved in. But there was a catch because he wanted to be part of their lives and they weren't impressed with his antics at turning into a snake that almost killed the new owners. When it comes to directing fantasy with a sane amount of special effects, Tim Burton is still the best on directing. Beetlejuice has just enough gore mixed with satire that the film is delightful without the scare.
The downside was a few loose ends, like wondering how Sarah played by Geena Davis, possessed the power to let the sandworm in, to swallow Beetlejuice when the ghosts were weaker than the worm. Another loose end was how the dead couple got siphoned back to the world of lost souls, although one could figure that something was needed to inform the couple that a mortal had stolen the “Book of the Deceased”.
The imaginative loopholes where the actors like Alec Baldwin and Geena Davis went in an out of the after world, added to the momentum and tension of the film. One suspected that the deceased couple would try to make an attempt to get the new owners out of the house but there had to be complications like the hazard of reverting to the help of Beetlejuice or the additional plague on the already deceased couple because of a meddlesome Otho.
An early performance by Winona Ryder crowned the film. She played a convincing gothic suicidal teenager with a special ability to communicate with the dead couple and acted also to inform her parents that the ghosts were unwilling to be used for show. She interacts with Beetle juice in order to have him remove a ghastly curse on the ghosts but had to sacrifice her celibacy to marry him.
The wedding is comical in the way it is dragged out and ended before it is sealed and so is the combination of special effects and comedy with scenes such as one of he final ones where Beetle Juice has his head shrunk because he switched numbers for some other freak waiting dogs ages to get into the after world.
