J. P. Harris, in his 2001 book "Time Capsule: Reviews of Horror, Science Fiction and Fantasy Films and TV Shows from 1987-1991", stated "While a marked improvement over "Watchers", "Watchers II" is hardly more faithful to the wonderful novel; 'improvements' by scripter Dominic include several plot flaws. But the kernel of both films and book are still there. The monster has an awful rubbery suit by Dean Jones and William Star Jones, which is ineffective even as a shadow. The film gives Singer an opportunity to be laughably macho. As in the book, the best scenes are of the dog, played by golden retriever Dakai, using a computer and other displays of intelligence."
