Here's one that has been driving me nuts, and it's super vague to boot. All I can remember is that theres a creature killing people. One of the people has a disease, and so they make spears with his blood in needles on the ends to kill the creature. The spears don't work so well, so the hero shoves the diseased guy into the creature. Having written that out, jeeze thats vague.
Anyway, I haven't thought about these movies in years, and you guys have pulled out some real classics. I remember the Eliminators was like my favorite movie when I was a kid. I saw it at Blockbuster some years ago and forced my friends to watch it with me. Ouch, that movie did not age well at all...
