How bad is it? It's extremely cheap, but it's effective.
Should you see it? If you have a strong stomach for both weird and gross.
This film from the Philippines is extremely violent and graphic and tries to make sociopolitical commentary with symbolism and shock - but it's basically just a sick joke. The family does in fact eat soil, but that's the least weird thing in the movie: bleeding undead poet, staggering man with cotton balls stuffed in his nostrils, cockfighting, murder, prostitution, drug dealing, clay animation sequences, etc. Essentially, the film is about the bonds of family... I think.
