Ghostbusters

Ghostbusters - in which three scientists pioneer a new, controversial technology and struggle with bureaucracy, inner and outer demons. Ray Stanz is a professional academic turned entrepreneur, getting mixed business advice from his best friends Pete Venkman and Egon, the nerd, about how to market their new ghost-catching technologies from their stately firehouse quarters in Manhattan.  Venkman falls in love with a client who had an appearance of the monster Zuul in her icebox, and he tries to impress her with history lessons about the Zuul, which I'm sure Ray and Egon prepared for him. They don't approve of his pursuit of the woman, but they know they can't stop him. Their business grows with the increase of paranormal activity throughout the city, so they bring on a 4th member to the team, Winston Zeddmore. It's technically 5 if you count the secretary Janine, and I do. So, Venkman goes to pick up the woman for a date, but she has been possessed by Zuul, presumably, and her neighbor across the hall has been attacked and possessed by Vince Clortho, The Keymaster. Zuul is the Gatekeeper. It's a sex magic thing. Okay, so after the cops bring the Ghostbusters the Keymaster, he escapes and makes it with Zuul, collapsing the top half of Central Park West, sending shockwaves through the city. The Ghostbusters, fighting the red tape of city hall and the dickless Walter Peck, had their proton packs taken away by the cops, and only get them back after Venkman convinces the mayor they could only help. What could it hurt? If they screw up, or can't fix it, they promise to go to jail. So, the Ghostbusters mount up, climb 40 flights of stairs, vomiting halfway there, and fight Gozer the Gozerian without much success, UNTIL, Gozer takes an Earth form of a destructor they choose. Ray accidentally chooses the Stay Puft Marshmallow Man (pictured). This monster of a Macy's Day Parade float is roastable, and the busters light it up with proton streams. Then its a Stay-Puft on fire. Not an improvement. Okay, so in a move of experimental science, Egon contradicts his previous instructions not to cross the streams, with a specific direction to cross the streams in an attempt to rip a hole in our dimension that they can push Gozer back through. Or Gozer will get sucked through, it seems like there is a vacuum on the other side of the hole they successfully create.  So, the monster explodes marshmallow everywhere, and the day is saved - thanks to the Ghostbusters!
