Leonard Maltin awarded the film 2 out of 4 stars, writing that the film "came to life during the last third of the picture".
VideoHound gave the film a similar score of 2 out of 4 bones. On his website
Fantastic Movie Musings and Ramblings, Dave Sindelar said, "I've never quite known what to make of this off-beat variation on the Dr. Moreau story. In fact, off-beat doesn't seem like the right way to explain it; it's not what happens that is unusual, it's how it is handled. It almost seems like it isn't trying to be a horror movie; the characters are fleshed out quietly and subtly, and it refuses to make easy moral statements or decisions. I don't think it's quite successful, but I think it's trying for something out of the ordinary". Sindelar concluded his review by calling it "one of the better horror films to come out of the Philippines". In their book
Science Fiction, Fantasy and Horror Film Sequels, Series and Remakes, authors Kim R. Holston and Tom Winchester awarded the film 3 out of 4 stars, calling it "atmospheric and spooky". In his book
Terror on Tape, James O'Neill wrote, "The first and best Filipino horror film, this grim variation on
The Island of Doctor Moreau is better than you'd imagine. Dank photography and good acting beef up this talky flick, which finally bursts into action in the last half hour". ==See also==
