I used to watch this movie as a kid. I loved it then and it is even better now. I like it better now because I can appreciate the production quality. The make-up and special effects were actually really well done. The plot was not meant to be complicated. The acting was good...because you believe the character (stupid or not). The reason that the survivors did survive is because they were the innocent ones. Horror rules state that the if you drink, have sex, or do drugs you will die. You sin and you die.
