I grew up watching this from infancy since I was born 16 years after the film was made. The ending has always horrifyed me in the way that some characters are revealed to be robots and almost everybody dies. It's like the shock you get with Hamlet where all of your main players get offed and how in Alien, Blade Runner and Westworld characters are revealed to be not human. Yes, Mad Monster Party is like Hamlet, Alien, Blade Runner and Westworld to me. I love it so much I own the soundtrack. Fantastic Holiday film.
