I bought a few dvds online. The first I've seen is Shake, Rattle and Roll 2K5. It's almost a waste of time except for a watchable third episode. The first two episodes relied on distracting and not very well-made CGI effects, the third relied mostly on practical effects, lights and shadows, great cinematography and makeup. Basically the aswangs are just people covered with lots of grease. It is almost a homage to Gallaga's Manananggal episode in the original movie. It also echoes Deliverance, even of the Wicker Man. It's not in anyway perfect but compared to the first two episodes before it, it´s a masterpiece.
