Round 1: Basic Plot

The Lost Boys is about two brothers and their recently divorced mother who move to a coastal California town—a place that they soon realize is crawling with vampires. The vampires then try and recruit the family into theirs, with bloody results.
The Monster Squad is about a group of friends who find an ancient book that reveals the world will be ending soon. So they must team up to fight Dracula, the Wolfman, the Creature from the Black Lagoon, and the Mummy to save the world.
These are oversimplifications to be sure, but the fact that The Monster Squad kids battle actual famous monsters instead of random, sexy vampires gives it the edge.
Point: The Monster Squad.
