Somehow this trailer hasn't been posted on this blog previously. How'd we miss it? Only the Gods can know. Basically, this movie rules. It's about a bunch of kids who befriend Frankenstein's monster and then fight off the entire Universal creature pantheon, sending them all through a gateway to another dimension. Also, there's a scary German guy who lived through Auschwitz. This movie is so awesome that last year there was a two disc DVD set called Monster Squad Forever! documenting its total awesomeness.
