I set my expectations low, when I saw the mainstream local actors were the voice of the characters. Its premise as typical cheap romantic comedy gives me a bad vibes because of reputation of poorly-made-overused plot lines that plagues Filipino mainstream cinema.
But I still give it a chance because Filipino animations are not common. I like the cultural references and the catch of the story. I think making it as adult, dark comedy animation film is a great move. In short "Hayop Ka!" Exceeds my expectations, 7/10.
