Before watching this film, empty your mind and just enjoy some 80's schlock. The film has a lot of charm that will surely appeal to fans of obscured horror cinema. Saying this about Forbidden World may seem like I'm stating its weakness. This is a s sleazy as Roger Corman films go, bad acting, cheap sets and plot lifted from Ridley Scott's Alien and add to that a lot of blood and gore with nudity and you have a cult horror film you won't forget. Clearly a rip off of Alien, Forbidden World is one of those obscured underrated gems that should be seen by fans of B movie flicks.
