I only remember few details about this movie. The opening credits was I think a spinning greenish vortex with the opening titles either coming out of it or going into it. There was some sort of green "blob or ooze" that moved around killing teenagers in a house. I remember it moving underneath a vehicle in a garage stalking some guy or girl. The key moment I remember is one of the last survivors confronted by the creature has no way to escape and he looks up,grabs the boom mike above him and swings to freedom. Any help and if it is currently available would be greatly appreciated! Thanks!
