The film is based on traditional Filipino folklore, and mentions creatures such as duwende (dwarfs), manananggal (winged, half-bodied vampires), aswang (blood-sucking monsters disguised as humans), kapre (tobacco-smoking giants).

Sorry, this movie sucks

This is a small, humorous movie in some ways, but it has a huge heart. What a nice experience.
Aubrey Hackett
While it is a pity that the story wasn't told with more visual finesse, this is trivial compared to our real-world problems. It takes a good movie to put that into perspective.
Janae Milner
Easily the biggest piece of Right wing non sense propaganda I ever saw.
