Return of the Living Dead: Rave to the Grave (2005)

An American horror directed by Ellroy Elkayem, starring Peter Coyote.
Interpol agents are looking for barrels of trioxin and the man who has some is killed when they test to see if it is real. His nephew is a college student who finds the other barrels that belonged to his uncle and brings them to a friend to find out what they are. The friend makes pills out of the substance and sells them to the local drug dealer. College students begin taking the pills and are on their way to a big Halloween party.
This was indeed not as good as the first few films. The plot was far more stereotypical and predictable. The characters were shallow, but this was a direct sequel to #4, which I could not get, so they may have been developed in that film. The video was generically stereotypical of crappy, new horror films as well. There was a strobe light scene at the end which typified this. The audio was also of inferior quality. I could hear the dialogue, but the soundtrack included terrible nu metal like Powerman 5000 and worse. Overall, you might as well skip watching this. I rate it poor.
